really reminds me of the old La Linea cartoons (youtube this). Mostly because of the interference of the artist with the characters and even being a character on it's own, even just for a bit. Story is cute too. Humorous love stories always score quite nicely. The short has a good pun too. There is nothing I would change here, just keep inventing new ideas. Real nice that you use plenty of classic none-tweeny animation too. I like a mixture of both, depending on the story or joke I want to tell. (My showreel is on here, so be sure to check it out if you're interested).
Well keep up the good work!
