Rocks...oh and cliffs!

I have been working a lot on my environment and level design project, thats what all the rocks, cliffs, foliage is for...but also I have been working on my zbrush skills for my class. Fairly new to zbrush still but I think I'm coming along good at it, anyways more pics below of things I've been doing lately.

I have done about 12 rocks so far but will only post 3 since a rock is a rock...all are using 1024^2 and are between 150-200 Poly's

Did a few cliff wall tests recently and I'm getting to a point where I feel confident making one my group will use for our cliffs in our level.

 

The Cliff in the scene above is the same as the one below, this screenshot is from Zbrush

 

This little guy is going to be my next Zbrush project, for my class we need to make a monster model, but the term monster is very very loose...so this is my stump!
