Nice photo, woody is sharp and well lit. The DOF is right. Would have been great if the background was not rocks, as it gives the overall picture too much of a brown look. A sky background would have then made it look like he was high up, and given that extra colour to the shot.
very good idea but pose is a little static...rock climbers use their legs a great deal. It would be more dynamic if you the closer leg was raised, and bent.
