1. its ok
2. great colors and angle
3. nice, my favorite. I'd like to see it without the black around the edges
4. would be cool if there were more color in the sky, and the flag doesn't line up right with the rest of the photo
im not diggin #1, its just uninteresting to me and the angle seems strange, #2 is sweet but i think a bit crooked (although it could be my eyes) #3 is awesome and #4 is uninteresting to me. good job with these my friend!
Cheers!
