Hm...
I imagine this could have been really great - if the background would have been more detailed. In another picture of you, I think it was the daughter of your Wh40k saint, the background served as a nice contrast and added to the dynamic. Here it seems like random shapes just thrown together.
Now, her legs are great, the way her hip tilts is great, her arms are alright, her head seems a bit small, which also makes her face a bit small. the shading is good, and the rope and her pose are really fitting for a dynamic picture like that. Overall great pose to present the character, all it's lacking is a background fitting Piona here, and some finetuning with the head/face.
