My favourite part was the homage to Who Frame Roger Rabbit.
There were a couple of okay gags, but I think it would have been better with a bit more energy. The narration and a couple of scenes seemed a bit slow.
I know you've already mentioned in a comment that you made this for yourself, so if you liked it then well done! However, it would be even better with a little work on the speed, timing, and energy of the voice acting (also the quality for certain voices). Some of the voice acting was really good, others were okay.
All in all though, good idea!
