Some of the variations below I thought might look better, and some turned out very, very well. The first image a friend of mine said the boulders looked like poo. :)
I can't say that I disagreed with them, though that was not my intent. Sometimes when you're playing with textures they just don't turn out quite the way you intended. Sometimes that's a good thing and sometimes...it's humorous at best.
I didn't save all the transitions of these 3d models as it is quite time intensive to do so, and I will on occassion, but for now just more interested in getting each model done and that requires a lot of time and testing.
