Nice, I quite like it.
I will say that there are several trees competing to be a dominant visual element, which I think detracts a bit. If they were not trying so hard to be dominant, you'd have more of an abstract texture, and if one was clearly dominant you'd have a clear visual hierarchy. Right now you have a sort of in-between picture. It fits with the slightly jittery feeling, so perhaps that's a good thing, though.
