Not bad.

It has a strong understanding of composition and of color scheme.

Line control is decent, but could really be better. I suggest you buy either a quill (my personal preference) or a professional set of fine-tip felt pens if you're going to work in ink. They'd really help getting in the fine details like the fishnet and the reflection on the hair.

The are a few perspective inconsistencies between items of clothes and the area that they're on, but the core anatomy (in the moe-anime style) is exceptional for your level.

Check local art supply stores, as well as craft stores. Some office supply stores even have them.

You can buy a nice wooden-handled quill with 5 or so replaceable tips for about $7, and if you do, you'll also want to buy a bottle of India Ink, which will run you about $3.

The great thing about quills is that you have immediate and complete control over line width. Just lightly pulling the quill across the paper (without pressing down) will leave a line thinner than any pen you can buy, while pushing down hard will leave a thick, extra-wide-tip-sharpie style line. With alternating pressure, you can make lines of alternating widths in a single stroke.
