Birch Tree Test Render 2

I highly encourage you to enlarge the picture and watch the video in 720p to see everything crystal clearly.
I played around some more with my tree trunk material and grass materials and managed to get something a little more natural looking I think. I rendered out a short clip to test my new 'render farm', where I render individual frames on multiple computers. On my main pc renders for this took around 16 minutes a frame and on my secondary pc renders took about 28 minutes a frame. Anyways, I didn't touch the actual texture or bumpmap at all, and I think the results are still halfway decent. Time to move on to other things ha.
