Pic 1 has a very nive composition and can clearly see the deatil of the fron and the back of the flowers... However, the flowers are to high inthe picture, and it looks like it was cut... You could photoshop this one, in order to add 50% more black on top and on the sides (that would bring some balance on the whole picture) and maybe try to see whether deleting the piede of leaf on the bottom would improve the quality (I personally like it with the leaf!)
Pic 2 does not have such good composition as the first, but is definitally the best photo (as they are presented here) - what bothers me about this picture is that you don't really see the "face" of the subject. This is not always negative (I know a lot of people you would prefer their face would never be photographed!), but in this case, I think it would be of advantage.
P.S.- Ok, I took teh liberty of editing your pic (I hope you don't mind) I personally think it improves a lot in the composition.. whyt do you think?
