Retro Pop Riverbank Key Visual

Using this character, create a retro-pop key visual. Use the reference image only for character reference; do not reuse the original image's composition, pose, background, or framing. Use flat-style anime shading with slightly thick outlines. Ensure the layout emphasizes negative space without excessive information. [scene setting] The composition should have three layers—foreground, middle ground, and background—to create natural depth. Place subtle elements in the foreground to add atmosphere, position the character as the protagonist in the middle ground, and keep the background simple to convey a sense of place and distance. Ensure each layer is organized to avoid information overload. The composition should not feel like a flat illustration but rather allow the viewer's gaze to flow naturally toward the back of the frame. Express the retro feel naturally through color palette, atmosphere, composition, and design sense, rather than using obvious symbols or explanatory text. Avoid excessive detail, high-density AI-style illustrations, particle effects, cluttered backgrounds, or harsh lighting. Aim for a clean, stylish screen organized like a poster.
