Mountain under the snow - A short CG sequence

Second sequence made for a school short film, we can see a snowy mountain with the stealthy appearance of the Silver Surfer (from Marvel) riding the mountain on his surfboard.
The goal of this sequence was to get the most realistic rendering I could do. It was a very complicated scene to put together, my goal was to really highlight the environment, I had a lot of fun working on this sequence, hope you like it.
