Hi Alex! Cool character you've got there 
You've got more skills under your belt than I did when I started my 3D major. Anatomically, you've done pretty well. In my opinion, the main areas that could use some improvement are the shoulders (a bit narrow) and the head, which is on the small side for the length of the neck.
It also looks like you're spending a lot of time in the orthographic views while modeling. This isn't bad, but remember to check your character's progression in perspective view too. My teachers were always telling us that our characters were too boxy around the edges because we weren't working in perspective enough.
Anyway, I hope that helps a little. Keep up the good work and good luck on your application!
