I think he said he wanted to end up using either BABS, or ((XABS)or whatever). If that's the case, he doesn't need this many characters...
I'm just saying...If he wants to use them as NPCs, I just "personally" think that is stupid. You don't need main character designs for NPCs throughout your entire video game. You draw one or two concept arts for each gender to each race, and use their concepts for your NPCs.
He doesn't really have anything posted about his game,(maybe a story here or there) so he is basically just showing off his mediocre artwork. All of his designs are human =/. He has way too many characters is my opinion...
