Very nice and realistic! Oh yeah, and I TOTALLY agree that the world isn't going to end in 2012. The Mayans probably thought that they weren't going to last until 2012 so they just stopped making the calendar.
Beautiful work, and pretty realistic, i suppose (i don't know, never been in space to see it! XD). 2012 will probably not mean the apocalypse and sorry, but for the moment, i have my own spaceart as wallpaper so won't use yours (now).
I think the lights on the terminator are a little bright, but otherwise this looks wonderful. And nope, nothing will happen in 2012, except another presidential election. Ohnoes. Excellent work, I love it!
