Wow the details on the belt and the necklace already look really great.
For my taste the thighs are a bit too big. But I can imagine how hard it is to hit the right proportions ... -> failed miserably at that when I tryed to "draw". It really takes tonns of practice and a lot of knowledge :/
On the other hand, everyone can tell that something looks strange when proportions are off, even if they can't really tell what it is -.- frustrating xD
But you are on a good track. As I said, the details already look super great.
Would not even get remotly close to this level myself ... I even suck at filling gaps with putty -.- ^^
PS: The left arm does really look very good. Every hour paid off

The right arm look promising so far as well. Thickness and length of the "segments" look right to me.
