Terrible overall.
Your anatomy needs an incredible amount of work.
Starting with the basics.
You failed to close the line at the top of the head, so it bleeds right into the tail.
The calves come off at seperate angles, which is physically impossible.
One calf even starts under the line, meaning the leg somehow started forming mid thigh.
You drew the breasts incredibly unshapely and rough, showing multiple juts that shouldn't be there for a smooth shape, such a breast.
The line work on the right ear some how meets up with what I'm assuming is the hair line behind the head causing it to look flat, and misshap
en compared to the other ear. I'm talking about the one with earrings.
Your shoulders are of two different sizes.
You didn't bother to account for a back on the character. Your use of extreme foreshortening has in fact cut this character's back side out completely.
The angle of the head versus where her hair fails over also kills her left cheek bone, meaning her head is deformed.
It doesn't look like you bothered to do much of a rough layout over all with the character, and I would strongly recommend you get the basic structure and anatomy of a character down before diving into the full drawing.
I would also recommend investing in a french curve, and lighter pencils so you have an easier time erasing.
You may also wish for shadows to use a shading stub, instead of just scrawling lines under the character, and drawing a line around the outline. It'll look a lot better overall.
