a few things to maybe do.
the rays you have over power some of the trees.
the bitch on the far left needs to be left out of this cover. find a new one and I bet the look changes. she aint sexy how she is posing. and her hands fade out.
the girl on the right side has a transparent glow that has a hard edge to it rather than a clean fade.
the three women are so big it hides the rest of the cover.
and like 3deanhq said, the solid font doesnt match well. try using innder shadow on large fonts like that to soften them up a bit.
you also have 4 fonts total which may be too many for how little wording is actually on the cover.
and like el toro said about the black on the bottom, using that gradient all the way around can create some real easy symetry.
I see your idea here though and it still has very good potential.
Keep at it and update us.
