I love the low angles you've got going on, especially in the third picture...
Some of these are pretty good, but some of them, in particular #1, 2 and 7 just seem to fall flat somehow. I can't quite put my finger on it, but something about them just seems blah. Perhaps someone who's more experienced could tell you. Hope that helps.
1) i love the idea...
2) you must try it again it wort for sure...
3) good job technically...
4) but something is missing... it miss the story in the pictures somehow... also the light must be more partuicular
Photo n3 my fav
