I dunno about this... I had a hard job as I had to use the PNG version of the sig as the PSD version wouldn't open... personally I like the v1 but tell me what ya think...V1 :V2 :EDIT:Heres a V3 :
v2 is better, but the dots on her face are bad. I know you couldn't fic that, but the changes you made were good.
Darken it, just a little... You can't really tell whats going on because its so light. I V2's effects and rihanna text.. You should switch umbrella with the song in V2.
Thanks for the feedback and also check out V3 its been sharpened up, given a b/c adjustment layer and curves adjustment layer... makes everything stand out a little more...
