Creating my first tree

Using the Maya tutorial in my previous post I began trying to mild a tree using some textures from the cgtextures website. I feel its not too bad for a first attempt. To get it more accurate I could bring it into Zbrush to mild the trunk a bit more or add roots, perhaps move the leaves around a bit more and redesign the top:

 Here is a crappy render - I had problems with Maya sun and sky on my computer, I think there was a missing file so the backdrop wouldn't appear :( will see if I can fix this, instead I chucked an image on a plane and realised afterwards that my tree was casting a drop shadow on it hahah...will fix this later :P
