Moe Pixiv-style melancholic concept art of an abandoned school courtyard at sunrise. A small, innocent-looking girl clutching a worn stuffed toy stands by overgrown playground equipment; distant slow-moving shadow-zombies beyond the gates (non-graphic). Soft pastel sunrise colors, warm backlight, long gentle shadows, cute emotional expression, soft painterly Pixiv illustration, high-detail, 16:9, high resolution, no text or logos.
