Drawing style: cute flat illustration, the kind used for planner stickers. Each drawing is built from several flat colour areas layered on top of one another: a base shape for the body and smaller shapes on top for the parts, so the inside of a drawing shows its own structure rather than one empty fill. Use two or three tones of the same colour — a lighter one and a darker one — to separate the parts and give the object depth. Small repeated marks inside a shape are welcome where the object has them: ridges, layers, grain, seeds, scales, stitches. Clean bold silhouette with smooth edges. No photo realism, no drop shadow, no cast shadow, no reflection, no glow, no outline drawn around the whole object.

Layout: every drawing sits alone inside its own grid cell with a wide empty margin on all four sides. No drawing touches another. No drawing overlaps another. Nothing crosses into a neighbouring cell.

Fully transparent background with nothing behind the drawings. No numbers, no letters, no words, no labels, no captions. No grid lines, no boxes, no borders, no drop shadow.
