Roll With It.
It seems that you really have grasped the cartoon style.
I'm liking it. But as I have said before get a little more in depth with the highlights, especially on black.
The characters will keep from looking so flat.
Since this is a still picture and not an animation piece, you can add a little more detail that would otherwise be daunting during an animation.
