Bicycle Frame Builder Portrait Steel Jig

For a bicycle frame builder portrait, place the subject in a bike frame fabrication bench. Build the scene around steel frame jig, torch set off, calipers, tubes, and weld samples, but keep the person as the first visual anchor. Wardrobe should include canvas apron, work shirt, safety glasses, and fingerless shop gloves, with small work details that feel lived-in and specific. Use directional shop light with metallic highlights and a palette of matte black, raw steel, burnt orange, and workshop wood to create a distinct atmosphere. The expression should communicate precise, independent, and tactile without exaggeration. Make the image useful for custom bicycle workshops, urban mobility, and maker profiles, with careful realism, clean anatomy, clear eyes, and plausible materials. Avoid brand logos, unsafe flames, impossible frame geometry, cluttered tools, fake labels, duplicated props, distorted hands, and any text that looks accidentally generated.
