Inside the industrial-style old warehouse, the gentleman is wearing a black one-piece work jumpsuit with a brown leather tool belt around his waist, hung with various vintage wrenches, screwdrivers and other tools. Wearing worn black leather gloves on his hands, he is tightening the nuts on a huge gear with force. His arm muscles are taut, and the veins are bulging. There is a little oil stain on his face, but he doesn't care at all. His eyes are firm and focused, immersed in the world of machinery repair. The graffiti and mottled light and shadow on the wall behind him add a bit of wildness to the picture.
