It's a still image in the opening few seconds, and it gets a little janky when they wake up, setting themselves upright, but there's a lot of promise in the stylization with the backlighting and overall atmosphere. I think when you become more comfortable with RIGGING, and redrawing limbs to account for anatomy being viewed from different angles, the rest will fall into place with practice.
I highly recommend experimenting with drawing, redrawing, utilizing onion skins, and looking into how the masters of animation did it in the past. Really good animation is a labor of repetition, and getting by on rigs can help with getting things done quickly, but it'll only get you so far.
Like Archer gets by on the rig-based animation because they got that finesse where assets will float on top of other assets to give the characters the appearance of being 3D. But when everything's one or few pieces, without that finesse, it's gonna look stiff and slow like a paper puppet show.
What'll get you ahead of the curve in your college studies is diving into Richard William's "Animator's Survival Kit." It's a book, but you can find it for free as a pdf online- Richard Williams is an incredible master of animation (Who Framed Roger Rabbit, The Thief and the Cobbler, and more), and that book is a TOME of knowledge when it comes to the principles of animation, so that your stuff can look a lot more alive. It helped me out a ton, and I think it'll help you too!
Keep at it, keep practicing, don't be afraid of quality- you're just getting started, and this is all practice.
