A bit awkward
I was going to give it an 8, but that seemed a bit harsh for the effort expended. It's rather close (in terms of accuracy) but it feels wrong proportionally speaking. I think the main thing is that the head is just much too big. I saw in one of the comments that someone called you a pedophile, lol, and I think that's because the large head gives it a childish sort of look. The figure's right hand also looks strange, The thumb seems to be missing half its length. I have a feeling this is just the result of overzealous shading, though. :3
In terms of formal elements, I think the composition is pretty powerful and dramatic, and it has a great plasticity and solidity of surface. The edge relationships aren't as nice as they are in your sitting female figure, and I think it has to do with the materials used. Pastels make a softer edge easier, while still allowing for crisp areas. In some places here the edges are too sharp and it tends to flatten it out a bit. See the transition between the figure's left arm and the torso especially.
Overall, a great effort. Most of the stuff I'm saying is nitpicky, but to me it always seems like the closer a drawing is in accuracy, the more obvious the mistakes are.
Like I said on the sitting figure, too, I'd love to see this in person. :)
