Replace “clean studio lighting with soft highlights and controlled shadows” with “dramatic raking side light with crisp directional shadows and a controlled specular highlight on the PVC.” Change “slightly muted safety-orange” to “high-saturation safety orange” if you also want the color to read more forcefully.

Replace “macro close-up” with “extreme macro detail centered on the stitch line and canvas edge,” and change “shallow depth-of-field falloff” to “moderate depth of field keeping the entire patch perimeter and surrounding fabric sharp.” Add “individual thread fibers, stitch spacing, and clearly resolved canvas weave” after “precise, neat stitching.”

Keep the fixed phrases “tan canvas fabric,” “clean studio lighting with soft highlights and controlled shadows,” “photorealistic commercial product photography,” and “macro close-up.” Replace “a circular swoosh-inspired 3D PVC patch” with a controlled subject slot such as “a shield-shaped mountain emblem,” “a rectangular utility label,” or “a star-shaped aviation insignia,” while retaining “muted safety-orange and deep charcoal accents” and “precise, neat stitching” across every variation.
