i like the cartoony style of it, but it doesn't really look victorious, more like angry or scared.

Reminds me of the Raving Rabbids ("lapins crétins" in French), nice one! :)

very funny. The eyes very much remind me of Garfield.

it's actually pretty good in its simplicity!

I like the animation, it's very effective considering how simple it is.

Great job. Simple can be as good as any other design choice.
