Cheers t1ck135! I've actually been considering bailing out on the idea of 4 arms. The more I think it out, the more 4 arms doesn't make sense. Not just in muscle structure but skeletal structure as well. 4 arms look cool but wouldn't be structurally sound.

Anyway, you're right about the knees. I havn't done much to the legs yet, but about to. There's still an ngon right above the knee I have to deal with too (and a couple near the crotch/naval). Trying to decide how many toes to give it.
