I think this would be a big nothing without the north star in there. It's a clear center to the image, and balances to a degree with the tree, so the composition is not bad. I think a different crop might strengthen that balance a little.
I find the effect of extremely long exposures on scenery to be extremely weird, the colors get bizarre and the light is weirdly directionless, even in the presence of strong shadows as you have here. I would probably de-saturate the hell out of the stuff on the ground, push it down much darker, and maybe do some burning and dodging on the major masses to suggest the lights that are present (you can see, for instance, two shadows on the tree, one strong and one weak. You could try to synthesize some modelling of the tree mass with burning and dodging).
I have NO idea if trying to put the directionality of light back in with dodging would work, and if it did you'd probably have to be subtle about it, it's just an idea.
Did you get a meteor in there are well? I might try to bring that out a little..
It's still probably a not much photo, these things tend to be novelties that, like all novelties, we tend to fall in love with.
