It's alright!
Well, the grahics were a little wobbly, but thats no real big issue, but the sound... Ugh. System of a Down rock, but in this movie it was way ahead of the movie itself, i know how to sort this:
Put the sound into a frame, go to properties. Set the Sync to "Stream", and the sound will play with the movie.
Another thing is you could include a Background to make it look like they're actually standing somewere instead of floating in a red space.
Your doing good, you CAN definatly get better!
