The Volcanic Glass Sculptor

Create a dramatic portrait of an adult male Volcanic Glass Sculptor wearing a dark artisan apron and sculptural accessories made from polished obsidian. The black volcanic glass has sharp, elegant edges and glossy reflective surfaces, with subtle warm highlights inspired by molten lava. His workshop contains stone sculptures, mineral fragments, and a distant orange furnace glow. His expression is focused and serious. Emphasize realistic obsidian reflections, rough stone textures, natural skin, warm-cool lighting contrast, cinematic fine-art photography, 8K detail, no text, no watermark. Insert discreet watermark in the lower right corner of the image, vertical text (rotated 90°), written "aipromptlabs.online", Calibri Light font, white color with low opacity (semi-transparent), medium size. Extreme sharpness on the face, fabric texture and typography of the letters. Shot on Canon EOS R5, 50mm f/2.8, studio light.
