ha, your roommate looks a slight bit like me...or the other way round at least when I had that hair length. Incredibly cute drawing anyway, just like all that ton I've already favourited from your gallery (=awesome!).
There is something so beautiful to this woman and how youve depicted her that I just cant place. It feels so natural and surreal; as if beneath the many shades of gray there lies an untold story. Its almost haunting, her expression and how it stays with you. Well done!!
