Made this today. Rendered with Blender internal renderer.
Interesting image, is it part of a larger story?
I think the textures look good 
why is the top of the door different from the bottom? does it open in a different way from a normal door or is it a design element?
Nice render 
I like it! Nice modeling, texturing and lighting.
Very nice,looks Twilight-ish.
The color scheme is awesome,and the water at the bottom ,makes it…strangely(is that a actual word?)dynamic:)
Looks like LOR.
Nice.
Thanks to all!
@Carbonflux: I must say I don’t have any story behind this one. Got the idea from a modelling challenge titled “A portal” and noticed it had already ended when I was about to post the image. 
Looking good.
…WHAT WILL HAPPEN IF SOME ONE OPEN THE DOOR!!!..
