A Glass of Water Catches a Drawn Fish

Generate exactly one original image, aspect ratio 4:5. An original mixed-media tabletop artwork photographed from a high oblique angle. On textured off-white paper, one bold charcoal fish leaps toward a real clear tumbler half filled with water. Its front half has crossed the glass rim and become translucent cobalt-blue glass underwater, while the tail remains a rough charcoal drawing connected to the paper by a sweeping black motion arc. A small splash at the boundary makes the action legible. Keep one continuous fish body, no extra fish. Soft side light, real refraction, dusty charcoal, generous negative space. No words, signature, or watermark. Text-only generation; no reference pixels supplied.
