Inks ar good for you. These lines are very rough, so I would suggest either working on improving your penciling technique to make them smoother or learn to ink. Overall the figure is ok, but it's pretty clear to me that it was made by just guessing how the lines can go, rather than knowing the real shape they should be.
Tell tale signs of this are the shoulders, particularly how the left arm does not have the right kind of cuver to the neck (should be more convex than concave, study yourself in the mirror), and the right arm meets the body at a very different location than the left does.
You have good visual skills and a steady hand, I like the hair and the face, but to improve you should study anatomy and use shapes to construct your images rather than lines.
The CG itself is pretty good, you have a good idea of where shading and hilight should go. The most important things to remember in CG are LIGHT and CONTRAST. The light source in this image isn't very clear, maybe front? More contrast would really help the image pop.
I hope that helps.
