Create a highly detailed, photorealistic 8K image of a robot on top of a rock next to a body of water, inspired by the Transformers toy series and the art styles of Gao Fenghan, Artgerm, Greg Rutkowski, Alphonse Mucha, Loish, and WLOP. The robot should be a biped, wearing full dress, and holding a battleaxe, with a focus on sharp textures and micro details. The scene should be set near a beach, with a beautiful, cinematic background that captures the middle of the ocean. The image should be in the style of a vacation photo, with a metalhead aesthetic. Use Unreal Engine 5 and Cinema 4D to achieve a smooth, extreme illustration.
