I really tried to come up with something that could improve the appearance of your logo, but all I could think of is giving the rabbit a pink nose.
Seriously though, it looks real nice. The placements, color, and soft shadow effects all compliment the image without over doing it. If I had to be absolutely critical, I would suggest softening the edges on the bunny rabbit.
Nice and simple.
No Neon colored confetti all over.
Cute little bunny rabbit.
