Oh crap... I shouldn't have looked at these, I was going to go through and draw every alien described in the books, and now my versions are going to be influenced by these drawings in someway. I hate that.
I'm not all the way through the books (currently at 36), but what is that one at the end, that looks like an Andalite, with the pointy head and red eyes? Is that and Andalite version of a chimp or something?
