I like it, the color of the sky is very nice, but I do have some crits..
I see great potential in your night sky. The scene is quite nicely set for some amazing astronomy. The white dots work, but you should probably make it more realistic, smaller stars, dimmer stars, etc.
Maybe you should "comb over" your grass so we can't see the ground, maybe make it look like it's blowing in the wind. Perhaps even add some light and make the grass dark green. There's a great tutorial on grass, I know that Nismo has done it with nice results:http://www.blendernation.com/videotutorial-the-secret-to-creating-realistic-grass/
Yeah, if it looked like that thumbnail except at night with and awesome starry display in the sky, I would create another account and vote for you twice.. Just joking.
It's a good job though. I hope to enter this one so you'll have some sort of competition.
