A crisp, anime-style 8K desktop wallpaper featuring a smart, cool teenage boy on the right side, casually holding a bass guitar and gazing up at a luminous midnight sky filled with a large moon and scattered stars; three-quarter view, slightly low camera angle with a gentle wide-angle lens feel to emphasize depth and the vast sky. Soft, cinematic rim and moonlight backlighting create cool blue and indigo tones with subtle warm highlights on his face and guitar. Background shows a quiet rooftop scene with silhouetted city skyline and distant neon signs, light atmospheric mist for atmosphere. Render in highly detailed anime shading with clean linework, soft gradients, reflective metallic details on the bass, and a dreamy, slightly painterly finish.
