产品视觉 GPT Image 2 提示词：Retro Pixel Mountain Valley

A highly detailed retro pixel art landscape of a bright alpine valley in summer, composed like a classic side-scrolling video game background but shown as a wide scenic vista. In the foreground, a winding tan dirt path curves from the bottom center into the middle distance through dense wildflower meadows, with a small blue stream at the lower right bordered by gray rocks and lush grass. Count 2 large foreground rock clusters, 1 winding path, and 1 visible stream. Fill the meadows with colorful flowers in vivid purple, yellow, red, pink, and white, with especially tall purple flower spikes on the left foreground and dense mixed blossoms on both sides of the path. On the left and right midground, place thick stands of leafy green trees and dark pine trees, framing the open valley center. In the background, show a dramatic mountain range with exactly 7 visible peaks: 1 dominant tall snow-capped peak slightly right of center, 2 medium purple peaks to its left, 2 smaller snowy blue peaks in the far center distance, 1 smaller purple peak to the right, and 1 cropped rocky mountain edge at the far left. Use vibrant greens and purples as the main palette, with cool blue shadows and lavender mountain faces. Above, render a bright blue sky with large creamy white clouds, halftone-dot shading throughout the sky and mountains, subtle vintage comic print texture, visible dithering, and crisp sharp pixel edges. Add exactly 4 small flying bird silhouettes in the sky. The whole image should feel colorful, nostalgic, scenic, and richly layered, with heavy halftone comic shading, retro print grain, no text, no UI, no characters, and no buildings.
