Just saw this. Obviously you managed to do some nice effects with the moon and the piercing rays of light, I liked them. However I'm not sure it looks convincing as a moon, and as a night scene overall. Everything's too bright. Maybe the sky should be much blacker, and the fog you applied too.
Night scenes aren't an easy trick to pull out, specially one heavily based on lighting effects such as a moon piercing light from behind clouds, so it's just natural that it's gonna give you more work. Other than that, the foliage is okay, a little bit too bright though, and the foliage in the background could be smaller and more clustered so it looks distant. Aaaand the light and cloud effects look pretty as I already mentioned.
