A highly detailed, hyper-realistic digital painting of a mouse standing on the bow with v8 engine, high-powered racing boat, on a tropical river. The scene is set against a backdrop of a lush, green forest on the riverbanks, with sunlight filtering through the trees and reflecting off the water's surface. The painting should showcase the mouse's fur, whiskers, and eyes in striking detail, as well as the intricate textures and materials of the boat and its components.
