This is a really great drawing so take what critisism i give with the knowledge that i am nitpicking. The clothing is fantastic, not sure if you got the idea from the guy whose comission it was but either way it is sweet. I think the buckle needs to be more side on if this is meant to be fully profile, and I also think you need to look at some referances for profile faces. The head overall looks a little too small and i can see a few buggy places at the chin and top lip. Remember that in a traditionally drawn face the eyes are usually (unless you are trying to stylise it) half way down the head.
Aside from my nitpicking, i really love the pose (i always love your poses) and the body anatomy is really fluid. I love the implied texture of the fur as well. Hope i've been helpful... if i had a character i would totally get you to draw it. If i thought i could get away with it i'd pay you to draw my assignment characters
