But you should add more FPS to get it smoother.
Your animation could be a lot smoother, but overall, it was interesting.
The Dreamscape was pretty cool.
But the song was very simple and the framerate for the animation was way too low.
It was good but ..
Too few frames per second, I dunno whether you have it set very low, but yeah I'd draw more frames or speed up the animation by raising the fps. Other than that, the actual positioning of the drawings was pretty well done, I knew what was going on. The drawings could probably be a bit more carefully drawn though.
