stylized-concept. Asset type: vertical experimental art photograph. Create a new 2:3 portrait image of a monumental transparent thick-walled U-shaped arch emerging from two smooth ivory-white sand dunes. Low viewpoint; the arch occupies the upper middle and is slightly left of center. A nearer dune rises diagonally from the lower right and partially hides the lower half of the arch; a second lower dune crosses the distant left. The sky is a vast uninterrupted deep cobalt blue with generous negative space. The arch is optically clear resin-glass with crisp polished rims, soft internal refraction, cool cyan-blue transmission, and controlled acidic orange, coral-pink and violet spectral light flowing inside the material. Simulate a restrained long-exposure photographic effect only in the colored internal light, creating smooth vertical light smears and gentle chromatic trails while keeping the physical outline sharply resolved. Clean hard daylight, pale high-key sand, subtle fine film grain, surreal minimalist editorial photography, convincing refraction and shadow logic. No people, no vegetation, no typography, no logo, no watermark, no border, no extra objects.
