The Oversized Lime Arch

Finished hand-drawn marker editorial illustration, square 1:1. Three chunky toy building blocks form one exaggerated arch, positioned slightly right of center in the lower two-thirds. Two squat dark-green cuboid supports hold an absurdly long bright lime rectangular beam. View from slightly below, showing the beam's underside with simple believable perspective. Rounded corners and gently uneven marker outlines. Textile-inspired decoration: a few broad woven-looking stripes on one support, large sparse checks on the other; the lime beam stays mostly solid. Flat sage and forest-green fills, pale mint highlight bands suggesting plastic sheen, warm cream accents along sunward edges. Pale green background, one broad soft grounding shadow, generous empty space above and left. Clearly legible at thumbnail size, expressive and deliberately simple, no intricate texture, hatching or photorealism. No people, text, logos or watermarks.
