A high-end sneaker advertising photo. Each reference picture has exactly one job:
Image 1 (white sneaker) = WHO. Keep this exact low-top shape, sole, laces and proportions.
Image 2 (koi fish) = MATERIAL only. The whole upper is made of koi skin: white with bright orange-red patches and a few black spots, covered in overlapping shimmering metallic scales. Do not show any fish, fins or water.
Image 3 (concrete stairs) = WHERE. The sneaker rests on one step of this exact brutalist board-marked concrete staircase.
Image 4 (sun through blinds) = LIGHT only. Hard midday sun through venetian blinds throws crisp diagonal stripes of light and shadow across the shoe and the concrete.
Wide shot, low camera, the sneaker in the centre, sharp focus, no logos, no text.
