Hi there, great start, a couple of remarks doh :
- The general anatomy doesn't look right, especially legs and face part. I think you need to refine the legs more, make the knees more visible. Her face looks a bit too flat.
- For the hair, do it in several elements, it will look less blobby, maybe you can go for a more manga style if you know what I mean.
- The pants need thickness and the top of the backpart should be a bit more higher.
- The boobs are personal taste

but the could have a bit more volume and more pointed inwards the body
That's it for now
