Yuki Sohma from Fruits Basket. I love Yuki! Mostly because he's the rat and I have two pet rats, one black and one white. The weird thing is I named my white rat Yuki (which means snow) about three months before I even heard of Fruits Basket. Coincidence? And really, my favorite character is Kyo because I love cats, and I love Kisa's animal form because I'm the year of the tiger. =^_^=
As for the picture, I didn't have a reference so I winged it. I think it came out much better than the Tohru one beside him. I won't show that one, it's horrid. That blank stare thing I do just doesn't go with her at all.
