头像壁纸：折纸棱面

Artistic avatar portrait of a young man's face folded entirely from crisp origami paper, sharp geometric facets replacing smooth skin, midnight-blue and white paper planes forming his jaw, cheekbones and brow, each fold line catching a razor-thin highlight, a small origami crane perched on his shoulder, deep navy paper eyes with tiny white fold lines, paper texture with visible creases and soft shadows in each valley, subtle fiber grain of the washi paper visible at macro scale, wearing a folded paper collar like a modern suit, calm thoughtful expression, plain warm-gray backdrop with a soft dark gradient behind the figure, single hard directional light from the upper right creating strong facets and deep crease shadows, blue-and-white palette, close-up head-and-shoulders shot, three-quarter angle, composed like a fine-art paper sculpture still life, macro paper fold detail, studio product-style lighting, high definition, 4k
