nice start! out of the 3 races I think the wild ones are the most interesting!
maybe you can push their uniqueness further.. maybe they grow up with a single beast that they tame and become partners?
since you'll only get to work on 1 character class, it might be better to show the entire race's personality in your concept/illustration. (in which i think beast taming race would be bad-ass!)
looking forward on more progress cheers!
