sketch of tin and some new character.

I've trying to design female characters and human characters over the past week, and in the case, both.
Sorry for the lousy sketch, I just wanted to post something. I'm practicing to get more complete works finished so i have more things suitable for posting to post. I'm really liking how this one came out so I might try coloring and inking this sometime, but I still need to figure out what color Tin is.
