I see effort . . .
. . . And that's always appreciated.
Sound would be nice, even if not voices. I imagine you have no mic, but you could easily find some decent low-key ambient music in the audio portal. That would help loads.
The art is cute. Could use fine tuning but over all, not bad.
Some of the "camera movement" was a bit weird, especially the part where you "swirl in" on the pumpkin. A simple zoom would have sufficed, or else you needed to keep the pumpkin in the field of view during the move.
Nice job for 20 hours. Good luck on future projects.
:D
