Steampunk Sun Queen Portrait

Vertical dark fantasy steampunk portrait of an ethereal clockwork sun queen, centered and framed from upper body to knees in a symmetrical sacred composition. Her face is intentionally featureless, concealed behind a smooth, muted beige square panel. She has long, flowing [silver-white] hair whipping outward in fine strands, and wears a voluminous white ceremonial robe with sweeping layered drapery and deep black shadowed folds. Her head is crowned by an enormous, dominant polished brass solar halo: a massive circular disk over the forehead with intricate filigree rings, micro-gears, radial latticework, small dangling star ornaments, and exactly 16 alternating sun rays (8 broad triangular spears and 8 thin needle rays). Across her chest rests a dark mechanical breastplate with 4 round clockwork medallions and beaded chains bearing 5 pendants: a pointed cone, a star, a gear-star, a pentagram ring, and a small orb. Set inside a vast, dim [gothic cathedral clock tower] filled with tall arched windows, bronze pipes, and 4 background timepieces (two large upper dials, a hanging clock, and an astrolabe). Cinematic chiaroscuro lighting, warm polished brass highlights against cool gray shadows, ultra-detailed engraving, shallow depth of field, eerie and majestic mood. No text, no watermark, no modern elements.
