Well, I like the character style you've gone for. It's awesome, and different from most I've seen on here. aside from that, I don't really have much to say from a critique standpoint, as I am not very experienced or knowledgeable in the way of the pixel. But...
I've been looking for someone to write a score for. My problem has always been the person I'm working with loses interest in their project. As you say you are doing this for university, my worries are much less in this regard. So! If you don't already have someone willing to work on music for you, I'd love to put some good time and effort into a bunch of nice tracks for you, if that is of interest to you.
