I watched part 1 first, as you said...
...and found it lacking, just like part 2. Somehow, it just doesn't manage to be interesting. The lip sync is indeed better but still off at most times, and not animating simple things like walking and such just doesn't do it.
Maybe with some more time you can perfect the lip sync, do some better voices and start working on more animations of the characters?
You have improved indeed, but I think that with a little more time you can do even better.
