I feel like you may benefit from killing the white space in some manner, and building higher saturation to create another, or add emphasis to existing focal points. Whenever I work with a wax, or paper medium, building tons of layers atop another can yield much deeper values.
I would also like to mention how her tail connects. You may consider developing a skeletal rig of sorts for placing bone structure, even in cartoons. At the moment, it seems to me that her tail stems from her right flank, and is angled very highly.
The color choice, and white along her hair creates a very unique style however, and I do enjoy the whites of the image, as they are very gradated, and add detail without adding noise.
However as a whole, I feel that should you develop more contrast and develop structure, your style will blossom.
