Jamming to the beat
What you did to her hair in the first picture caught my attention right from the start, and what the first image lacked in glow is well made up for in its second iteration. It's also interesting to see how the burning building around her changed from the first to the second picture, but the way it looks in the end leaves me with nothing to remark at. Exquisite, if anything else.
Her face and back is rather bright, however, as if there's another light source behind the viewer. But with the intense fire going on in the back, the things facing away from it would still appear darker by comparison, so it may be something to consider. The dress in the latter image confused my sight several times as well, or to be specific the lower right corner, but if it has less highlights (like in the first image), then the issue won't be as big. I'm not familiar with the character though, so if her dress actually glows on its own, then this whole paragraph is less solid.
Also, what's the deal with the pixie dust?
