Nice!
Okay, I'm going to try to ignore the whole sickening cheesy aspect of the pet names here (because that really watered the whole thing down and made it obnoxious), and focus on the movie itself. Your animation was great, and the humour was splendid, especially with the stuff going on in the background. The voices were funny (although a little annoying because of the slllooooooowwwww spppeeeeeeeeeeeed at which they spoke). Overall, well done, and overall I liked this animation a lot.
I understand that this was a lovely parting gift for your girlfriend, but please consider leaving the cheese out of it for the rest of us next time -- unless it pertains to the movie itself. There was no obvious romance between the two characters in this movie, so there was no reason for the mushy extras.
That said, I'd love to see more of your work. This was really good and really funny.
