illustration-ink-sketch

Draws hand-inked cartoon critters and living objects as SVG cards (480x360), each acting out a coding or design idea. Identified by thick black brush-pen outlines that swell and taper and break into separate strokes, loose marker-and-watercolour fills that slip past the line, diagonal hatching instead of solid shadow, huge googly eyes with two specular dots, and stray ink hairs and flecks, in tomato red, leaf green, sunflower yellow, sky blue and teal on white. Covers palette, brush numbers, mascot construction (eyes, blush, mouths, 3-finger hands), props, ground patches and a tested, seeded brush kit. Use when asked for ink sketch, hand-drawn, brush pen, sketchy, doodle, marker or watercolour-cartoon illustrations, googly-eyed mascots or critters, playful empty states, onboarding, 404 or error pages, loading states, blog headers, feature spots or marketing cards.

# Illustration: Ink sketch

Sketchy, hand-inked cartoons: a googly-eyed critter or object (a snail, a pair of worms, a potted cactus) whose body carries the coding metaphor, drawn with a wobbly brush pen over loose marker colour. It suits playful product moments: loading, errors, greetings, conflicts.

Boundary: for clean, even ~2 px ink outlines on people with flat fills, use `illustration-outlined-cartoon`. For people drawn with a black brush marker and one mint second colour, use `illustration-two-colour-brush`. For soft, unoutlined cosy animals with grain, use `illustration-grainy-gouache`.

Extracted from a set of 42 original design-and-coding cards in 14 styles; the three cards in examples/ are this style's shipped cards.

## The look in one sentence
Every edge is a filled black brush polygon that swells from about 1 to 4.4 px and tapers to points, laid in a few separate strokes over a colour fill that slips 2 to 3.6 px past it, with dark areas hatched rather than filled.

## Palette
Measured from the examples. Each colour family is base / dark / light; the dark goes into mottle and marker streaks, the light into one lit streak.
