nice cut-marks in the wood, and the semi-circle grain. it would look better if you were closer to the subject. the lines would fill the shot, and the teeth of the saw would feel more forboding.
Looks like a sharper blade is in order! I like this shot. It doesn't make me think Construction entirely -- I'm curious about what's being built here. I think I'd see Construction more clearly if it were a 2x4 or 2x6 or something more than just a surfaced plank. 5
Look at those burn marks...better get a sharp blade and cut through the wood instead of burning through it...j/k actually. Interesting shot, and nice close up. <5>
Very nice composition. Interesting and uncluttered. Good dof. By the looks of those burn marks on the wood though, maybe the blade needs to be sharpened? hehehe
