fantasy crab 3d model

Create a highly detailed 2D illustration of a monstrous giant crab, strictly based on a hand-drawn pencil sketch reference. The creature has a wide horizontal body, massive segmented claws, thick articulated legs, and a rough spiked exoskeleton. The head is embedded in the center of the body, with grotesque organic features: multiple asymmetrical eyes, skull-like facial structure, hollow cavities, sharp tusk-like mandibles, and an intimidating, unnatural expression. Maintain the original silhouette, proportions, and pose from the sketch, but clarify, refine, and complete all unclear or unfinished areas, improving anatomy consistency and visual balance. Style should be clean 2D lineart, inked drawing, fantasy creature concept art, slightly exaggerated shapes, no realism. Apply color using dark reds, browns, rusty oranges, and muted organic tones, with subtle shadows and flat or soft cel shading. No 3D, no photorealism, no textures like render or CGI. White or transparent background only
