the texture of the leaves is perfect, I reckon you nailed it :) The only thing I'm not a fan of is the colour pallette, I guess it's a certain style but I prefer different shades of green and brown :p But don't take that as critism, it's just my option and to each his own :) really cool piece :D

I've desaturated the greens a bit, and edited a little here and there...

Thanks a lot hnt6581, Dredlockz, Mikebissle and Geolm for your kind words!

Geolm, you have a good point. I was a bit unsure myself of whether the green might be a bit sharp. I'll have a look at that later.

Great tree, although I would prefer a bit more desaturated leaf color

Good job on the leaves. :D

 really nice!

Great one! Everything is just right, no constructive criticism needed on my behalf!
