Help with this cartoon? Does it sound original?

I'm a cartoonist and I have spent the past year creating an original cartoon. In the cartoon, a talking muffin named Mr. Muffin, his roommate/best friend Kip (whose a talking cat) and a 30-year old centaur named Jonathan go on crazy adventures serving as the royal guards to Princess Blanka meeting crazy characters such as pieces of toast, a used juice box and a lot more characters in the land of WTF fighting off dangers such as Teh Bunneh (an evil rabbit who has a grudge against Princess Blanka) and Lucifer, ruler of the Underwhere (sort of like Hell) and leader of his demon army. The comic is a comedy and is sort of like a darker version of Adventure Time. But that is where the problem comes in, is the brief description I gave a bit TOO similar to shows like Adventure Time or Regular Show? I looked to those shows for inspiration but not for the whole idea. I really think this would be a funny kids show and I want to get it noticed. Please respond, but don't be too harsh thanks!
