I think the rendering is really nice. I also like the color palette. I feel like the stomach are could be a little bit longer because it feels like her chest goes almost immediately into her pelvis, but the main problem I'm noticing is the leg going backward.
It's a bit of a tricky angle, but right now it looks like she's both bending her leg backwards and sideways which is weird.
I think an angle like I did above would work better. It seems like the position of the foot is probably the main issue, but I think part of the shading of the leg also create the illusion that the leg is in the wrong angle.
So that would be my main critique. Keep up the good work!
