I can see you're leaning toward cartoonish, it's a nice style and I think it's very cute.
The shading is nicely done, not too much so it doesn't smother, but you can tell where light sources are within it.
Again, you might want to work on hands, since the finger aren't even. In fact in cartoon style, most people only make the hand have four finger, since it looks more cartoony.
Only thing you may want to consider is a different head style, since it's frequently used in animes. Cartoons typically use a geometric shape as a head base, like a circle, an oval, or even a triangle in one case.
