Tight, symmetrical close-up portrait of a serene cybernetic humanoid head with closed eyes, a weathered metallic faceplate mottled with patina, oxidation and subtle scratches, an ornate central gem set into the forehead emitting a soft amber glow; intricate mechanical ear modules and layered brass-copper gears nestle at the temples, a thick ornate collar of ringed, engraved metal encircles the neck with visible pistons, tubing and micro-screws, exposed mechanical throat components peeking through; palette of deep teals, cobalt blues and burnished golds, dramatic cinematic rim lighting and soft volumetric backlight suggesting a swirling nebula, faint embers and smoke tendrils in the background, high-contrast chiaroscuro, ultra-detailed textures, hyperreal close-up, macro detail on filigree, corrosion, tiny rivets and solder seams, epic, reverent mood evoking an ancient biomechanical deity, shallow depth of field, 8k, photorealistic, highly intricate.
