10 Common Mistakes Authors Make When Hiring a Book Cover Illustrator
🇬🇧 English version
Introduction
Every month I receive messages from authors who have already spent time and money on a cover, only to be disappointed. The story repeats: they chose an artist based on a low price, didn't specify rights, skipped sketch approval — and ended up with a cover they were ashamed to show, or had to redo from scratch.
This article is not theory. These are concrete mistakes I see in my practice as an illustrator with 71 verified reviews on Reedsy and covers for HarperCollins, Hachette Livre, and Hoëbeke. Each mistake comes with a real example and a way to avoid it.
Mistake 1: Choosing by price, not by style and genre
Real case: A fantasy epic author found an illustrator for $80 on a freelance marketplace. The portfolio was beautiful — anime-style portraits. The result: the cover looked like a Japanese RPG poster, not a fantasy novel for a 35+ audience. The book flopped at launch, and the author reordered a cover from another artist for $900.
Why it happens: Authors think "drawing a picture" is a universal skill. But book cover illustration is commercial genre art. An artist who draws beautiful portraits may not understand the visual codes of dark fantasy or sci-fi.
How to avoid:
Rule: better to pay 40% more for an artist who "lives" in your genre than to save and get a result that doesn't speak to the audience.
Mistake 2: No contract or unclear rights
Real case: An author paid $500 for a cover, received a JPG file. A year later, they wanted to publish the book in Germany — contacted the illustrator for permission. The artist demanded an additional $800 for an "international license." The author had to either pay or change the cover.
Why it happens: Many authors assume "I paid for it, so it's mine." But in illustration, by default the artist retains copyright, and the client receives a license. The scope of that license must be clearly defined.
What should be in the contract:
Standard practice: exclusive license for use within the book and marketing — included in base price. Full rights transfer (work for hire) — doubles the price or more. Source files — at extra cost or in premium package.
Mistake 3: Trying to please everyone instead of the target audience
Real case: A thriller author assembled a focus group of 7 people: mom, wife, programmer friend, accountant colleague, two neighbors, and a cousin. Everyone gave different advice. "Make it brighter," "Add more colors," "It's scary, remove that skull." The cover became a gray compromise mush without character. Amazon conversion dropped 30% compared to an A/B test of the original version.
Why it happens: Authors confuse "I like it" with "my audience likes it." A cover is not a family voting subject. It's a marketing tool addressed to a specific reader.
How to avoid:
Rule: a cover should evoke emotion in the target reader. If everyone likes it, it probably doesn't evoke anything in anyone specific.
Mistake 4: Ignoring typography and layout
Real case: An author received a stunning illustration — dragon, castle, lightning. But when they added the book title in 72-pt Impact font over the center of the composition, the dragon disappeared. The cover became "a picture with text," not a unified design.
Why it happens: Authors think the illustrator will "fit in" text later. But a professional cover is designed as a whole: composition leaves air for typography, the color palette doesn't conflict with the font, hierarchy leads the eye from title to image.
How to avoid:
Rule: illustration is 50% of a cover. The other 50% is font, layout, hierarchy, spacing, balance.
Mistake 5: Micromanagement and pixel-level revisions
Real case: An author demanded 14 rounds of revisions. "Move the eye 2 mm left," "Make the shadow 7% darker," "Add 3 more highlights on the armor." The illustrator burned out, final quality dropped, the author was unhappy. The project took 4 months instead of 4 weeks.
Why it happens: Authors think more revisions mean a better result. But every revision round is not free. It exhausts the artist, destroys cohesive composition, and pushes deadlines.
How to avoid:
Rule: strategic decisions are made at the sketch stage. The final is polishing, not reforging.
Mistake 6: Choosing an illustrator without a sketch stage
Real case: An author paid a 50% advance and received a "finished final" after 3 weeks. The dragon was green, but the author dreamed of black. The character looked left, but needed to look right. Background — forest instead of ruins. Result: complete redo from scratch, 3 weeks lost, advance lost.
Why it happens: Some artists (especially beginners) skip the sketch stage to save time. Or the author thinks "the artist is a professional, they know best."
How to avoid:
Rule: no "straight to final" projects. Sketches are insurance for both sides.
Mistake 7: Not checking the artist for plagiarism and "ghost art"
Real case: An author found an illustrator with a gorgeous Behance portfolio. Paid $600. A month after publication, they received a letter from a lawyer: the cover used fragments of a Shutterstock illustration without a license. The book had to be pulled from sale, a fine was paid, and a new cover was ordered.
Why it happens: Some "illustrators" sell other people's work under their name (ghost art), use unlicensed stock, or pass AI generation as hand-drawn illustration.
How to avoid:
Rule: if the price is too low for the quality — it's likely not original work.
Mistake 8: Unrealistic expectations for timeline and budget
Real case: An author wrote: "Need a cover for epic fantasy with 5 characters, a dragon, and a castle. Budget $150. Timeline — 3 days." Received 40 rejections and 2 responses from beginners who made a cover from stock images. The book launched with a cover the author later hid on all platforms.
Why it happens: Authors don't understand how long original illustration takes. A professional cover is 20–60 hours of work: brief, references, 3 sketches, detailed rendering, revisions, typography, file preparation.
Realistic benchmarks for 2026:
| Price | $300+ | $600–1,500 | Stock, plagiarism, low quality |
| Timeline | 2 weeks | 4–6 weeks | Artist burnout, mistakes |
| Sketches | 1 round | 2–3 options | Wrong composition |
| Revisions | 1 round | 2–3 rounds | Conflict, budget overrun |
Rule: a good cover is never cheap and fast. If you're offered both — verify 3 times as carefully.
Mistake 9: Ignoring platform technical requirements
Real case: An author received a beautiful 2000×3000 px cover, uploaded it to Amazon KDP. The system rejected it: no bleed, text too close to the edge, print resolution insufficient. They had to pay a designer to redo it to technical specifications.
Why it happens: Authors think a "beautiful picture" is all you need. But every platform (Amazon KDP, IngramSpark, Google Play Books) has strict technical specifications.
What to know in advance:
Tip: before ordering, download a cover template from the platform where you'll publish, and send it to the illustrator. This will save hours of rework.
Mistake 10: Lack of communication and feedback
Real case: An author disappeared for 3 weeks after receiving sketches. The artist waited for feedback, deadlines were missed, the author returned demanding "where's my cover?" The project stretched to 2 months, both sides were stressed.
Why it happens: Authors think "I paid, let them draw, I'll come back in a month for the result." But illustration is a collaborative creative process. Without feedback at every stage, the risk of error multiplies.
How to avoid:
Rule: the illustrator is your partner, not an outsourced contractor. The tighter the communication, the better the result.
Checklist: how to avoid these mistakes
Conclusion (EN)
These 10 mistakes are not abstractions. They are stories from real authors who came to me after a bad experience. The good news: each of these mistakes can be prevented with 30 minutes of preparation before ordering.
A cover is not decoration. It's your primary marketing asset. Invest time in choosing an illustrator, and the result will pay for itself many times over.
If you're planning a book in sci-fi, fantasy, or horror — I'd be happy to help you avoid these mistakes from the start. My process includes a detailed brief, 3 sketches, 3 revision rounds, and full rights transfer for the book market.
