I really liked it; very creepy models, and generally just really well put together.
One slightly easier way of solving the jerkiness problem would be "double-framing" or animating in "twos" - animating twelve frames per second, duplicating each frame, and then playing back at 24 fps.
That said, the jerkiness of the animation didn't bother me at all in this, I think it suited the style well. The only thing I think would look better smoother is the camera moves - the opening shot in particular stops very suddenly.
Anyway, I thought it was great, would love to see some more!
