Very sweet work!
I'm very impressed. Your style is very cute (even the 'gangster bunnies' are cute!). I love how well you're able to capture different angles and perspectives with fluid movements of both the environment and characters. The syncronization to the music is very well done, just like the first "There she is!". Also, the birthday theme is sweet, and I'm glad to see that the cat guy isn't (too) shy another the girl bunny anymore. =)
Very touching and cute sequel. I definitely look forward to more of your work!
