The illustration problem
The manuscript is done. The illustrations are why it's still a Google Doc.
You finished the story months ago. Your kids love it. You've read it aloud to test the rhythm. But you can't draw, and every illustrator on Fiverr quotes $100-200 per spread. A 32-page picture book means $2,000-6,000 before you've even uploaded to KDP. The good illustrators on ArtStation charge more, and their portfolios don't match the style you see in your head.
You tried Midjourney. The bunny on page 3 doesn't look like the bunny on page 12. The characters have three fingers on one hand, five on the other. The style drifts page to page. The book reads like a collage, not a world.
Pick an artist. They design your characters once, then draw every page. Same bunny, same world, cover to back matter.
Why it fits children's books
Built for the book, not just the cover.
Characters that match page to page
The main character on page 1 looks like the main character on page 28. Same proportions, same expressions, same clothes. The thing AI illustration usually breaks, we hold.
One artist for the whole book
Cover, title page, every interior spread, back cover — all from the same hand. Reads as a designed book, not a collection of images.
Warm, expressive, age-appropriate
The catalog has artists who specialize in children's illustration — soft palettes, readable expressions, gentle compositions. Not stock art. Not corporate clip art.
Book 2 uses the same characters
Writing a series? Same artist draws the same characters across every book. Readers recognize the world. The series looks like a series.
From manuscript to print
From a story in your head to a book on the shelf.
Tell us about the story
Open @slop. Share the manuscript (or a summary), describe the characters, name three picture books whose style you love. A paragraph works.
Character designs come back
Within days, 4-8 artists pitch character concepts. You pick the artist whose style matches your vision.
Characters get locked
The chosen artist finalizes character reference sheets — front, side, expressions, poses. These become the bible for every page.
Spreads ship page by page
Cover first, then interior spreads in sequence. Same artist, same characters, consistent world from title page to the end.
Print-ready for KDP or IngramSpark
High-resolution files at print spec. Same artist available for marketing graphics — Amazon A+ content, social, author website.
Project shapes
From cover-only to a fully illustrated book.
Some authors need just a cover. Some need every spread. The brief flexes.
Front cover + character design
Cover art and character reference sheet. You handle the interior or plan to add it later.
Full 32-page illustration
Cover, title page, 14-16 interior spreads, back cover. The standard picture book format for ages 2-6.
Chapter illustrations + spot art
Cover, chapter opener illustrations, spot art throughout. For chapter books where text carries more weight.
10-14 pages, simple spreads
Thick pages, large art, simple compositions for the youngest readers.
Multi-book character lock
Same artist holds the characters across books 1-N. The bunny in book 3 matches the bunny in book 1.
The math for children's book authors
What a picture book costs to illustrate. What it should cost.
| Approach | Typical cost | Time to finish | Character consistency |
|---|---|---|---|
| Professional illustrator (ArtStation, agencies) | $3k-$12k per book | 3-6 months | Excellent — but expensive and slow |
| Fiverr / freelance platforms | $100-200 per spread ($2k-5k total) | 4-8 weeks | Variable — depends on the artist |
| DIY with Midjourney / DALL-E | $20-50 / month | Weeks of prompt iteration | Poor — characters drift page to page |
| OKSLOP brief + retainer | Subscription — see plans | Weeks for full book | Locked to one artist; characters stay consistent |
Costs are rough market ranges, not quotes. A subscription covers character design, cover, interior spreads, and marketing graphics from one credit pool. See plans.
