My posts always come with the caveat that I'm just a beginner myself, and I'm doing this in my lunch break. I hope you get the idea!
I love the shapes of the legs and feet, and the hair outlines. Some good work there. There were a couple of things I wanted to have a go at though:

Instead of pillow shading the hair, a technique I see a lot is adding highlights with rough edges in the direction of the hair strands. It brings some life and body to the element and suggests texture. There's usually a lighter shade doing the same kind of shapes over a larger area as well. I added a shade for the highlights, as white looks too glaring.
Her left arm (our right) looked way too long! With that hand I'm trying to do as little hand work as possible, so it wraps neatly round the shaft and out of the way where our eyes can't see it!
I see what you mean about claws though! Very difficult to get good shapes. I've added a lighter shade to help define the "fingers" and another one nearer white for the claw tips. I'd like more time on this, I'm not 100% convinced about it myself! Three claws looks more alien to me though, and is easier to draw.

Finally there was a fair amount of noise in the teeth and not much information. I simplified it a bit and tried to suggest a little bit of an indent from the plane of the face. It may not be to your taste.
What I didn't have time to work on:
I think her left calf and foot need looking at as well, shading-wise. With the relative lengths of the thigh and lower leg, the left foot should be going quite a bit backwards from the knee. That would mean we'd see the top of the shoe as it braces against the ground, but we see the side. This ends up making my brain think her left leg has a very short lower leg and a very long thigh. In general, making things darker when they're further back (and brighter in the foreground) helps... If you want me to show you what I mean, let me know.
