Kin Daku & Ace- Request

I drew this in mechanical pencil and then inked it in with a sort of gel type pen I guess you could say...but, anyway, this was a request from a friend...well, I kind of told her I would do it for her anyway since her friend Cody said he wasn't going to do it due to one of the reference pictures she had for him. I am going to try and color this, but I don't know if I can promise you anything, so.....
