Retrato de rainha celta com torc dourado em fundo preto

Professional YouTube thumbnail asset, bust portrait of a Celtic queen, Rhiannon, Bronze Age aesthetic, wearing a golden torc necklace and dark tribal furs. She has long dark hair, intense mysterious eyes looking directly at the viewer with a subtle, cunning smirk. She is holding a small, ancient leather pouch near her chest. CRITICAL: Isolated on a solid, pitch-black background. High contrast, clean sharp edges, no background details, no complex textures behind the subject. Dramatic cinematic rim lighting separating her from the black background, hyper-detailed face, 8k resolution, photorealistic dark fantasy style. --ar 16:9
