Nightly anguish

This looks great! Also, your style seems really promising. 
I'd give you a few ideas to consider though, as I believe what is great in this can become amazing!

So, I think you should really emphasize the main model here. As it is, colors are too similar and she feels more as part of the background than the main piece of the composition (I believe that's what you were going for). To do that, maybe you can add more shadows behind this pillar of bodies that she's standing on, work more around the contrast and add some brightness to her, so that she's really the first thing your eye catches when you stare at the pic.
Also, I'm not really sure what's going on in the background. There seems to be a forest, but also a giant fog, a lightning and a crow. These could all work well together, but we need to make it look more coherent. The forest is fine, but the fog could really lose some opacity. Setting it to 30% ~ 20% might really help. The lightning, though fine as it is, seems really distant and far away - but in the pic, it looks like it's right by her side! If we shrink it and put it, I don't know, between the trees, for example, it should look much better.
Lastly, there seems to be a bit of a fade effect on the bottom of the bodies. That feels really odd, but it might be what you wanted (It's totally cool if it was, though)

I know critics hit harder than compliments, but I hope you take these in consideration. I want to see what you're truly capable of!
I'm eager for your new posts.

Cheers!
