1. WAY too much wall and not enough person. You cut off his hands. Focus fell short of the subject. Try posing him to the left of the frame and getting wall on the right if that's what you want.
2. My fav other than the head chop and elbow chop. Nice colors even if a little dark.
3. Overexposed. Colors are off.
4. Pretty cool. Wish he was more to the left of the frame and more in focus, though.
