looks pretty good, i like the environment although it could use some more texture and maybe better lighting, of course you might be limited here due to rendering times. The barn roof looks a bit messed up, not sure what's wrong with it..
The animation was quite good as far as i can judge animation, although I think it was way to slow for final animation, it would be better if you had some variety in speed, sometimes anticipation can be very useful but at the same time things happening/ moving quickly can look great as well, so you should really find a balance between those two things.
