Great
For a first attempent , it's stunning. Bravo. You learned really fast.
The idea was good and the music well supported by the pictures design.
Take care of some details, though. The trees, by example, are not just slidding from one side to the other. The jump back and fort, and it's a bit disturbing for the eyes. Also, I'm in the impression you cut the song and put pieces of it in differents scene while making your movie. The music jumps a little when you change scenes. Instead, you should animate all your scene and then put them all on the same seen, with a specific layer for the music. It will goes smoother.
Nice lipsink with the vampire. It's hard to do and you did well for a begginer.
Continu and you'll get really good at it.
