This striking image captures a massive submarine navigating through an underground canyon in a scene that melds the visionary styles of Katsuhiro Otomo and several other notable artists like Jean Giraud (Moebius), Roger Dean, and Hajime Sorayama. The submarine, a central focus of the composition, moves through dark blue waters bordered by imposing red rocks, creating a symmetrical and cinematic feel that reflects the best practices for AI image generation. Detailed textures and dramatic lighting enhance the undersea ambiance, while red details, including moss growing on the rocky walls, add a vivid contrast to the scene. Cel-shading, flat colors, and line art blend seamlessly in this concept painting, evoking the unique aesthetic of Otomo’s Akira and capturing an epic, timeless adventure beneath the ocean’s surface.
