Hmm
First of all, why did you select some strange R&B song to play throughout the video? Maybe it wasn't R&B at all but it sure sounded like it.
As for your animation - it was pretty well done. I notice you used stock photographs to create your backgrounds and that seemed to work with your foreground characters and such. As for the characters themselves, did the witch have to be so cliche. I mean, green skin? It was sort of distracting because it amused me and broke the rhythm of the storyline.
Generally speaking, it was pretty well done. Good job.
