I think that you have a really unique style that I enjoy a lot (great colors, and simple but unique character modeling) and your themes are always playful but just a little sad: which I love! (love your zombie character)
I can't think off-hand of anyone who has a similar style to you, but that's a good thing!
Cartooning can be as diverse as the cartoonist chooses to make it: it's all a medium to express a message, and not just a direct message but a message wrapped in an emotion.
