mechanical fish 3d model

Follow the silhouette and all the lines of my sketch as closely as possible, but make the fish look very organic and detailed. Keep a slightly boxy, cardboard-like overall structure, while the surface of the fish is covered in many small, realistic scales. Use realistic blue and white tones, with natural gradients and subtle color variations. The skin should have a wet, glossy, reflective look, like a real fish, with physically based, shiny textures. Give the fish large, highly realistic eyes with depth, reflections and moisture. Add a darker, more gory and realistic twist compared to the drawing: include several organic-looking holes and torn areas in the body that reveal parts of the spine and inner flesh inside, while still matching the shapes and markings of my original drawing. The final result should stay faithful to the drawing’s design, but look like a detailed, realistic 3D model.
