That looks like a pretty good start. The face is probably the best part at the moment, though it doesn't seem that you spent as much time at all on the other bodily features. For example:
The hands are a very odd shape. The hand all-together is a bit unrealistic. If I were you I'd correct the proportions with a reference image of a drawn or real hand to give you good shape. This is the same with the whole body, reference images are always very helpful!
Arms don't normally ever jut outwards, though perhaps this is an anime styling? With it this way though, it would be very hard for anyone to animate!
The breasts look very much like extrusions and do not fall naturally. They also seem very squarish, I would work on rounding them and having them fall naturally on the character.
You could also pay a bit more attention to the boots, they're okay, but could use more details like the face, and more attention in refining what you have.
You're definitely heading in the right direction, and don't take these criticisms harshly, I'm being picky at the moment to help you to try and improve this model.
