First of all, the view, for me, it's a basic portait of one of your character, but in a nice pose.
This kind of pose is not very original, but also quite difficult but you succeded to deal with it.
The technique can progress, you know it, but it grows quite fast. The details are deeper, the shadings more real and the expression excellent. You still have problems in proportions, but you don't need me to progress and also to make the shading more even (more shadings on the head than the body).
The impact now, this art shows me all the effort and progress you made, and thank to this drawing, I can see how much you went forward, I was immediatly impressed when I saw it.
