I dont have the sketches nor could i ever help you with finding them... like i said, its been years. I am sure that after this year they will release them when they are more ready with it.

What I do know is that I remember seeing one of the sketches for thirteen and they seemed to have a few new "species" or "races" of humanoids in the works... the sketches were just sketches but it does seem that they have some amazing creatures to come ^_^
