Brian K. Vaughan style reference and prompts

The illustration has graphic-novel clarity with sketchy ink contours and muted watercolor-like fills. Olive, khaki, stone gray, and small rusty accents settle into a weathered palette. Angular built forms and broken light planes are interlaced with dark organic clusters, creating dense but readable depth. Firm outlines hold the central silhouette, while finer hatching and patchy color describe rough surfaces without photographic polish. Side light picks out pale edges and leaves deep cavities under overlapping forms. The overall effect is grounded, tense, and quietly post-apocalyptic.

A square graphic-novel illustration shows an older gray-haired man standing on broken concrete steps among overgrown urban ruins. He occupies the center of the frame, wearing dark sunglasses, a short gray beard, a muted green field jacket, camouflage trousers, a utility vest, and sturdy brown boots. One leg is planted high on the rubble while the other stays lower, giving the pose a watchful, ready balance. A long dark rifle hangs down along his right side, with the barrel nearly touching the lower edge. Behind him, pale damaged building walls rise at sharp angles, their windows dark and partly broken. Thick green vines climb across the façade and spill around collapsed masonry, softening the rigid ruin with dense organic growth. A few reddish leaves or small accents appear among the green. Chunks of light concrete and black cracks frame the lower foreground, while the upper sky or wall remains a restrained pale gray. The man faces forward, and the dark lenses conceal his eyes; the face is defined by firm inked lines and small shadows in the beard. Light comes from the upper left, lifting the edges of his hair, vest, and concrete while deep shadows collect inside windows and under foliage. The color has a washed olive, sand, and slate range, with sketchy outlines and patchy watercolor-like fills rather than glossy rendering. Fine hatching supplies texture to fabric and stone without crowding the clear silhouette. The overall composition is grounded and tense, using the single upright figure to connect human survival with the layered decay of the city.
