Very nice lighting/exposure. Depending on your exact "trade," I wonder if a shot of the backs instead of th palms would have worked, and been a bit more unusual.
While this does fit the challenge, and the photo is well taken, I'm not getting a strong "wow" sense from this photo. Are you an insurance salesman? (joke) I would think this more effective if you included something in the way of hardware tool that helps these tools do their job (did that make sense?) 7 Swash
