As an awful apology for replying to your message a literal half year later, I thought I'd leave a comment here before anywhere else and try to help you out.
Your hand drawings are amazing, far better than any hand drawings I could have done. But your general body anatomy doesn't match the technical beauty your hand drawings have. In the post without armor for example, her but is huge! I see that it would stick out in a pose like that, but it gives the impression that even if she stood up straight it would still be huge. I'm all for big booty girls, but not if their anatomy is actually incorrect! XD
In addition, I think the leg farthest from us is longer than the closer leg. Looking at the armored figure, the design is great. I can't fault it. But the left arm looks bent in a way that makes me think the elbow is dislocated, and the way the shoulders connect to the neck is slightly off. I think it's that the neck is just a little too short.
That said, I love your figure sketching in general, it's full of life!
