The first I think lacks something - not quite sure what, I think its because the water drop have nothing special to it - I like the idea though.
The second I will admit I really really like! Its composition and lighting really appeal to me. If I were to be critical I a would say that the far petal is a little too overexposed and some of the finer details present in the others is lost. Almost looks like something one would expect to see in Final Fantasy CGI.
