This is a promising piece with attractive artistic choices here and there. I like the atmosphere, too.
But I didn't really understand much of the action taking place, or how that spear was even being swung, with sparks and flame down in the floor and yet the tip being up in the air, as if the speed of the swing had been lightning fast- enough to break those bones like a twig.
Here's some edits of mine to the poses, with the goal of making the action more obvious and dynamic-looking... It's far from perfect but it may give you some clues.
If you want to work over this one, go ahead, it's yours.
