Prompt
A photorealistic studio photograph of a hand-embroidered textile artwork presented as one irregular fabric slice, centered on a perfectly flat, evenly lit matte pale-seafoam surface with no texture and no grain, uniform in tone to every edge. The slice holds one small complete night-sea scene stitched entirely by hand: a whale's body rendered in flowing satin-stitch fills of deep and mid blues swimming through rows of French-knotted waves, a pale gold thread moon above, and a few small star knots scattered in the dark fabric sky. The fabric edges are part of the work - dense finished stitching along most of the border that gives way to a few frayed, unraveling thread ends at one corner. At its boundary the piece ends the way handwork ends: loose thread ends, one needle resting against the fabric, and a couple of escaped knots trailing onto the empty surface, so the artwork looks finished at its heart and unfinished at its rim.
The slice sits fully inside the surface with generous flat breathing room on every side; the pale-seafoam field stays perfectly smooth, evenly lit, and identical in tone to all four borders, suitable for extending the canvas by matching the flat color. Soft directional light rakes across the raised stitches, casting tiny thread shadows within the slice only. No text appears anywhere. 16:9 wide composition.
