The completely blank background bothers me. If I didn't know this person was welding from the title I could have assumed he was doing something else. Of course, there is the fact that he's wearing a welder's mask, but the picture doesn't say "welding" to me. The most effective shots of welders, imo, are those where the welder is in a dark environment and is illuminated by the welding torch. In this shot the sparks look like they could be paint splatters. They don't look like light-emitting things.
