Sabata,
I don't think I'm being picky, on the 6th screenshot you can clearly see the seam when the texture repeats.
If you're supporting alpha leaves cool, however, if you use masked leaves you should use a different texture for the leaf so you don't get the black outline.
The bark texture on screenshot 2 needs to be fixed as there is a pale detail on it, this makes the whole tree look very repeated, remove this pale detail and it will look fine. Likewise on Screenshot 4.
As I said, it looks great, I just think these issues need to be resolved.
