A really nice idea and a good realization. looking at the pictures used before and after they are nicely blend together, also the overall blurring effect on the girl is absolutely great.
Considering the water brushes which were used from my stock, this is the first time I have seen someone use them in such combination, and it makes me wanna see more of this.
The only thing which is not so nice is that the water drops standing a little bit out of the picture and don't blend so well, but I know that this is quite hard to achieve because I tried it also many times by myself.
Keep the good work up, hope to see some more pictures from you were you use my resources.
