Those are amazing shots
I didn't know an XTi could be this good.
While I was glancing through your shots, I was thinking, "Wow check out the balance on this one..and this one.. so on.." I do like like the clarity + the lighting + timing = Professional results
Your timing is perfect with the action and everything..Gosh I wonder how hard you positioned yourself for the angles haha thats pretty hard for the soccer photos. Overall, I like the drama in your shots--drama is all about the lighting, (and I would say you got the perfect White Balance.)
If you don't mind, I'm curious...What specific lens did you use for the soccer photos??
