Alright...
In most cases, this was very well animated, the drawing was good, and the lip-synching was excellent.
However, I do believe that in areas that this is a little unfinished. Fow example, there are areas where you have used still drawings only, where some animated drawings would have made it look so much better.
I can also understand the white kind of canvas look you have gone for in most of the scenes, but this makes it look also a little too unfinished. Maybe some light and simple backgrounds would suffice, just to make this animation look 100%
Other than that, good stuff.
