#1. nice shot, I like the concept. However, it doesn't make sense to me to focus in the middle of the gun. I'd have focussed on either the guy (about were his eyes are) or the very end of the gun. Or just increased the sharp area.
#2. nice, but average. And yes, the pole is leaning... (It's pretty hard to get that right IMO.)
#3. I can't really see anything interesting in this shot, also looks a tad unclear to me. Like the shadow of the bush though.
