Jim - very nice. I would clone out the vertical mark in the backdrop on all but the last one. It looks like there is a spear coming into his back. On #1, there is also a line coming out of his butt that I would clone out. Did you do these "in studio" or "on site"? Lighting?
I did a shoot of a 10 year old Dane girl on Saturday. I'll post some of that grand old lady after I've processed them.
Again, very nice shots of a handsome older boy.
