Asgardian Thunder God: Etched Warrior Portrait

A hyper-detailed artistic portrait of a powerful warrior resembling a thunder god, with short rugged hair and a thick beard, looking upward with a determined expression. His face has dramatic red war paint streaks running vertically across one eye and down his neck. He wears futuristic Asgardian-style armor with metallic shoulder plates and a red textured cape. The artwork is a mix of sketch engraving and digital illustration, with fine linework and etched textures. Background is minimal with abstract runic symbols and scattered glyph-like text floating around. High contrast lighting, cinematic composition, desaturated tones with red accents, ultra-realistic details, poster design style, 4K resolution.
