Actually half decent man, I like it.

Not big on the render, but you've made it look really good with that atmosphere.
Only thing I'm not sure about is the ponytail, looks like it was roughly added in.
Pretty sure if it's just how the render came, but it just looks weird not having any black detailing.
Don't blame you for not touching it up, but that would make it.

Lighting is well, along with with the colors.

Would love to see the render become more involved with the background though.
Maybe smoke/clouds kinda blending in with the left side, fading out.
Not something necessary, but it shines out on this kinda sig/tag, whatever style it is.

The particles work well with the style, and story in a way.
Would be cool to see what it would look like with some blur on some, to differ it up,
and it would add some sort of motion effect.

I like the city thing you got goin' in the background, actually looks good in the background.
So nice job on that.

Last thing I'll touch on is this:

don't really get what it is, but it keeps drawing my eyes towards it.
It's just strange, with the rough "s" looking shapes.
(no big deal though)

All in all looks good man, nice job,
