咖啡館磚牆邊的單車，墨線只畫到一半

Square 1:1 frame, a realistic studio shot of a pen-and-ink illustration. The artwork is a freeform cut-out vignette sitting in the middle of a matte pale-cream ground: perfectly flat, evenly lit, with no grain or texture and the same tone all the way to each edge. Within the vignette lives one small, self-contained scene drawn only in solid black line: a vintage bicycle with a wicker basket is propped against a cafe's brick wall under a short striped awning, and its shadow falls on the paving stones as hatching. All values come from dense, confident crosshatching and shifting line weight, with short broken marks for brick, long clean strokes for the metal frame and bold awning stripes left as bare white paper. There is no color anywhere. Toward the vignette's boundary the drawing fades the way ink naturally does: hatching thins to sparse straight lines, a few contours trail away unfinished, and tiny ink spatters dot the blank ground, so the heart looks finished while the rim looks unfinished. Keep the vignette fully inside the ground, with wide flat margins around it. The pale-cream field stays perfectly smooth and evenly lit, its tone identical along all four borders, so you could extend the canvas by matching that flat color. Soft, even illumination; the slight sheen of the ink is visible only inside the vignette. No text of any kind.
