Well these two are nearly done, I've made some changes to the Scotts Pine (geometry for the needles rather than image maps) and about three quarters of the way through a mature Ash Tree, little work on the UV mapping and I think the branches could do with being a little smoother.
I like the one on the left. :D could you do one that's bent like the one in Luc's render here?
@cyphyr - These are marvelous as is. Downloading pleasure coming up. ;D
looking good Rich...can't wait!
