I've been studying like a madman recently and haven't had time to do my regular Thursday upload routine. However, I did not stop playing around in Blender and PhotoShop; I'm now going to optimize my models by using normal maps when appropriate rather than adding in 5000 polygons for wrinkles that come out very faint anyway. The next big thing I've learned to do is add, cut, comb, etc. hair on my models in Blender. I'm trying to add hair to the new head crab model to make it more disgusting.
