Nautilus mechanic

THE PROMPT

An original small nautilus-like mechanic with a rounded spiral shell and two expressive eyes repairs a brass water pump inside a transparent sea garage. A tiny tool belt wraps around the shell. Sea grass and soft coral silhouettes outside, clean appealing character proportions, witty serious expression and polished animated-film materials. No lettering. Visual medium: Polished stylized 3D character rendering, appealing original proportions, tactile ceramic or soft organic materials, careful shape design and physically coherent light. Palette: deep teal, coral orange, electric blue. Lighting: underwater caustics and a warm workshop lamp. All human or humanlike figures are clearly adult and fully clothed. Original character and object designs. One coherent finished image, with no added lettering, logos, signatures or watermarks.
