I love Zarracka's expressions in this page. You can feel her haughty irritation at the arrogance of her opponent. The last three panels are by far my favorite though. The way the air just roars into Zarracka's mouth, like a hurricane in reverse, really drives home the sort of power those lungs of her's are capable of. The way her chest slowly puffs up as she inhales is rather delightful as well, I must admit. Something tells me that fire beast is in WAY over his head.
As always, your use of colors is nothing short of stunning. Stupendous stuff!
