Nice models! There are lots of tutorials on creating organics, I'm actually working on that for a school project at the moment. What software do you use? I may be able to point you in the direction of some good resources. While I like the location in the desolate area the fact that you put them in the two dwarf areas doesn't make much sense! Perhaps a map expansion would be necessary to incorporate them into the game world.
Signature made by yours truly but inspired by the art of Aametherar the orc. Taking requests for sigs, PM me.
