아바타 배경화면: 모래로 빚은 얼굴

Photorealistic avatar portrait of a young man's face formed by pouring golden sand, cascading grains streaming down from his dark-brown hairline, his features sculpted in smooth dunes of fine sand, deep brown eyes with grain-textured irises, sand particles drifting in the air around him, a thin stream of sand still pouring from above his forehead, ripples and mini-dunes forming along the neckline, wearing a collar of undulating sand waves, calm focused expression, the backdrop grading from warm beige to soft umber, plain warm beige studio backdrop, single directional beam of sunlight from the upper right illuminating each tumbling grain, grains glinting as they fall, a fine dust haze glowing inside the beam, golden-amber palette, close-up head-and-shoulders, three-quarter angle, macro sand grain detail at desert-gold warmth, time-lapse sense of motion, high definition, 4k
