This is actually really good
I really loved the way you layed the scenes out economically and tried not to waste any work. I love how you used real hallways and had the character walk in and out of the shot, then continue through a cut to the next hall. It was like the viewer could actually map out the house they were in, giving it a touch of reality.
I also enjoyed the style of the characters limbs and in the film in general, the proportions were realistic yet their forelimbs were shrunk which to me kind of emphasized there limbs movement which was well animated, looked like it was done over a real person running as a template. Kind of like a stylized realism, really cool to see people doing that more.
