Err... your face, I think the 'meanie' has arrived.
What is with the tiling light textures? That looks DISGUSTING. No nice to way to put it.
And, why is there crystal in your map? If you're making a cave/natural map, use a crystal textures. If you're not, do not us it. And, what the heck?! There's a fan 'stuck' in the crystal that shouldn't be there? What on this earth is that?
I'm teh meaniez.
