New materials for new game

To build our new game, I needed to create two new materials that I didn't have.  The first was snow, and the second was crusted lava.  3DS Max 2011 comes with a lava material already....but it sucks and it looks more like diseased alien skin.  Also the snow looks like bright default material.  So here are 2 test renders of the materials just so I could get an idea of how they look.

Snow Material

Crusty Lava
