Well, I saw the video now...
I can tell you invested alot of time on small details, small rocks, etc. I like this, beauty lies in small details, imho. But the main picture is no less important... you failed in recreating a realistic environment.
But the biggest flaw of this scene, is specially the lighting, you could have achieve a much better result with this scene's lighting, played with fog, and so on and so forth... the scene just looks, too dark!
What's that covering the moon? And why did you covered the moon in the first place?
nevertheless, It's a good achievement, keep up!
