This is good. I have a few problems though:
One:The trees are pillow shaded. (It means they have more than one light source, that's a big no-no)
Two:Frame number 45/44 (Depending on your editing program) is the same as a frame farther into the animation.
Three:The scrolling is very off, and choppy.
But I'm going to give this a rating of 6 because it's a very good animation, and it's very long.
It was fun to watch. Very nice. :)
