Galaktischer Walhai Poster-Illustration

A single-subject digital illustration of a celestial whale shark swimming upward toward the upper left in a graceful vertical crescent arc, isolated on a clean solid white background. The animal features a large rounded head with mouth slightly open and a calm eye, curving down into a broad body with its tail fin at the lower left. Exactly 7 visible fins: 1 large dorsal fin on the upper back, 1 smaller rear dorsal fin, 2 side pectoral fins, 2 small lower pelvic/anal fins along the underside, and 1 broad crescent tail fin. Style is a smooth semi-realistic 3D painterly form with soft luminous shading and glossy skin. Instead of natural markings, its body is filled with a vivid galaxy nebula texture of saturated cobalt blue, violet, magenta, cyan, and warm pink-orange gradients, sprinkled with countless tiny star speckles and bright starbursts. The snout glows with warm pink and peach tones, transitioning into blue and purple along the body, accented with turquoise highlights along the belly. Crisp edges, ample negative white space, no water, no bubbles, and no background scenery. In the bottom-right corner, subtle black handwritten script reads "[July 30, 2026]" above "[Oyagi]".
