Bright palettes and silly shapes win hearts fast, so I usually begin with a playful brainstorm where nothing is off-limits: fish with bubble-trailing top hats, fin-shaped wings, or tiny gardens growing on their backs. I sketch quick character sheets — front, side, three-quarter — and jot down three words that describe the fish (curious, sleepy, proud). Those words keep the design on track.
From there I simplify. Children's books demand readability: clear silhouettes, bold color contrasts, and facial features that read at thumbnail size. I pay special attention to the eyes and mouth because expression drives empathy. Try variants with round, crescent, and
almond-shaped eyes to see which emotion comes through best. I also test how the fish looks in motion: is the tail expressive? Do the fins act like hands? For printing, I make one high-contrast black-and-white version and one printed-color mockup to catch any issues. Materials matter too — digital brushes can mimic watercolor washes, while flat vector shapes are fantastic for clean, modern titles.
Story integration is the secret sauce. Think about what the fish will do on every page and design elements that can be reused — a glowing fin that illuminates dark scenes, or a pattern that doubles as a map. I often create small activity spreads (coloring pages, sticker sheets) from the design so the character feels multi-dimensional. Drawing for kids is a lot of fun because you can be bold and silly and still teach something gentle, and that balance is exactly what keeps me excited.
