Excellent.
There wasn't a whole lot of new scenery, and the scenery there was was simply linked together and looped, (e.x. the cliff scene), but it was still excellent.
The fox was drawn exceptionally smoothly, and you did a great job giving it facial expressions. Each and every last one was very cute.
It's also been years since I've heard this song... So props for nostalgia as well. ~<3
