Nice work! I like the quick figure studies and the face/portrait studies. With the figure drawings I might suggest spending a bit more time with the proportions before moving in to the more finished linework.

Looking through all these images I suddenly feel so inadequate about my own portfolio (I'm applying for Character Animation and I did do the admission test and interview, but compared to you... ugh...) But it's also very motivating! I really like your work, there's some beautiful stuff in there. The backgrounds are particularly good! Good luck with your application.
