Mask work of the woman is too sharp and angular as though you used the polygonal lasso. There are several tint shape layers on the figure which make no sense as though they are off register. The straight right side of the tree where the image ends makes it obvious it's pasted on, you could fix that with some careful cloning, the tree shouldn't be so sharp either it should match the softness of the rest of the image at that distance. The moon should be softer as well. I think you could improve your entry if you would work on these basic problems.

I think the dark shadow from the hill to the ground needs to be more gradual/subtle. AS it sits now, I think it's too powerful and takes away from the image. I also agree with spaceranger's comments. Good luck. I will hold my vote in case you decide to make changes.

It a nice entry, I see were you going with this, if your going to re-edit the image, don't forget to put the moon behind the clouds. Cause the moon is in space, not in the atmosphere.

The woman fits better. Maybe use the burn tool to give her a cast shadow and also darken the left side of her body since the light source is coming from the top right. When you are making the cast shadow keep in mind where the light source is coming from. Keep working on it and you'll have a cleaner image. Good luck!

The concept and the composing of the image is very nice, but some things are wrong.First, low the contrast of the moon adding some blur on it. Moreover I think there's too much light on the girl and on the track she's running on, thinking about the moon should be the only source of light she should not be so shiny. Things will change if a car is behind her! Sincerely, i would modify a lot of things, but I don't know where to start from.
