I like the detail in her armor. It looks like she's coming from a mountain and that she trained with her Dragon Masters. The red in her hair, eyes, lips and skirt sash may show that she has fire within her; however, the gloves show another power that she has. The curves of her legs and body are nice; however, I don't see much of a knee on her left leg, and how she twists her torso looks like she's twisting just may be quite too thin. Oh and the dragon heads be represented on her shoulders, head, and maybe gloves (well at least from this angle of her) looks really cool. I like how there is less focus on the rocks and the smoke and it's mainly on her.
It's beautiful work, but I can't help thinking there's something slightly off about the placement of the right leg, specifically the curve of her butt.
The other problem I see is the relative position of her torso. Trying to replicate that pose gives me a severe pain in the region of the floating ribs on the right side, and that's before trying to hold my arm back and out or twist my head around to match the angle of rotation seen here.
