It shows some promise.
I used to work in stop motion animation, so I have some experience here. What you'd made shows that you have the most important quality in creating good stop motion animations; an interest in improving. As you continue to make more animations, you'll start to figure out on your own what works and what doesn't. I can point out a few things that need improvement here. Firstly, you need consistent lighting. Don't stand in the way of the lights when snapping a frame. Also, and most importantly, the more stable you can keep the lens, the better. These are things you'll learn as you continue, though. For now, this is not so bad. You probably noticed that it took longer than you expected to create such short animations, but you'd be better off putting in more time to create a more complete and satisfying finished product.
