Chân Dung Than Chì Người Đàn Ông Trầm Ngâm

A fine-art charcoal and graphite portrait of a handsome man with [thick, dark curly hair], leaning his head against his hand in an intense, pensive pose. Lit with [deep chiaroscuro lighting] creating dramatic highlights across his facial contours and forearm, with the background dissolving into [heavy, textured black charcoal strokes]. Rendered on textured sketch paper with visible cross-hatching, softly blended smudges for depth, subtle jaw stubble, and reflective moisture in his eyes. Monochrome, high contrast, moody, and cinematic.
