I like the lighting on the skeleton a lot. A couple of things I could suggest - the stars all have a very similar brightness (on this crappy monitor anyway, so this may not be an issue) which sort of makes them look more like illuminated snow flakes than a distant starry night which has a whole range of star brightnesses. The second is that the skeleton is meant to be a ghost - perhaps playing with the transparency of the skeleton would make it match the story closer (but you may lose some of that cool lighting you've got going if you do this, so this might be a bad idea). The other thing is - the moon looks an odd shape - i.e. sort of oblongish rather than circular - this might be some bryce weirdness to do with your POV - not sure.

Pretty good pic all over though - I've always found night time pics real hard to get looking right, but you've done well in my opinion.
