Retro cel animation style, with clear thick black outlines depicting characters and scenes, flat color blocks combined with soft gradient shadows. Warm orange, grass green, and dark green create a high contrast color scheme, while the background features watercolor-textured hazy trees and a light blue sky. Character designs exhibit characteristics of 1960s-70s Japanese animation, with big eyes, round faces, and simplified features, resulting in an overall elegant and nostalgic atmosphere, reminiscent of a European art film narrative.
