Keep in mind that I have never done any animation work. Well not anything significant.

I think that perhaps there is not enough light in the scene. I know it's supposed to be dark. But just a little bit more lighting might be nice inside the house.

I like the animation, it is a bit jerky here and there, in other words I feel like it needs to be smoothed out a bit. It's not 100% necessary, but it couldn't hurt.

Outside of that it's pretty interesting.
