Wonderful colors, and very reallistic (although I understand it is not done with a picture). It's on the edge between a drawing and a photograph, just pulling you in because of this movement illusion created by the white spots. Also the focus contributes to the effect. A pearl of nature opening up to the light and rain, pure and strong, not willing to give in easily. Beautiful.
I know apophysis, and I even worked with it for a while, but I never have seen such effect. I guess everyone finds its own way to create art with it. Still I think this is a very beautiful piece of art.
