Um.... Well, you can't do unarmed fighting before the second floor, as you need to unlock the Extra skill [b]<<Martial Arts>>[/b].
Just go ahead and use claws after you find some or buy some in the RP.

Anyway, I don't see anything wrong with your CS at the moment. Just kind of waiting on the stuff you plan to update before I really give an all around okay. But since you want to post before you decide that, I am fine with accepting it for now and then seeing you update before giving you the 100% okay.
It looks fine to me, but wait for Caits input.
I doubt Caits will reject it though, unless I overlooked something.
