A pretty nice ride, funny idea, although you can tell it was made in 3 days.
How about making this animation again, only this time, take 6 days. You already have the storyboard, now focus on making everything look a little sweeter, add some shade to the characters, some detail to the background. For example, a wooden frame around the door, and fix the '2 shades of blue' background wall! (decorations, a see-through window)
Might sound like a drag, but it'll be a great comparison, and maybe you can add some other gags while you're at it!
