Good skit ideas.
Well done on variety of characters even tho they were simplistic.
Good job on the lighting of the scenes too.
This is some great stuff but as you said it needs improvments.
you should improve on:
Transitions and transition sounds. BTW the Donkey Kong start music thing was okay.
Alternate poseing of the characters.
instead of : P to pause and Space to play there should be small buttons on the video.
What is Warrior cats is it good?
