1. the extreme diagonal makes me seasick
6. looove the moon, very pretty The plant on the foreground is a bit too close to the moon for my feeling
7. i like how the dark corners and the red jacket pull you to the center. Maybe it would be nicer if the face and the guitar would be a little less bright/overexposed?
8. has a really different feeling. Feels much flatter in a way. Did you use a flash?
9. very nice. Because i'm trying to train myself in doing it right, i notice the horizon not being horizontal. Might be nice if the building and the horizon are straight and not falling over.
10. his facial expression is confusing which doesn't really help the picture
11. nice how you combine the low plants with the high clouds. Makes it a bit more unnatural.
