Ретро-поп аниме-арт на берегу реки

A retro-pop anime key visual featuring the character from the reference photo. Use the reference photo solely for character appearance, with a completely new pose, composition, and background. Setting: [A riverbank in summer. Sitting on a grassy concrete step, gazing blankly at the river with a half-eaten ice cream in hand.] Composition: Poster-like layout emphasizing negative space across three organized depth layers. Subtle atmospheric elements in the foreground, the character prominent in the middle ground, and a simplified background establishing distance and guiding the viewer's gaze naturally backward. Style: Flat-style anime cel shading, slightly thick outlines, a nostalgic retro-pop color palette, and graphic design sensibilities. Clean, uncluttered composition without excessive details, particle effects, or harsh lighting.
