A warehouse or smth.
Edited, of course! No photo without Photoshop :D
p.s.: Why is this the second edition? Because the first looks like this: http://mihaibrrrr.blogspot.com/2007/10/warehouse.html and it was posted at a time when I didn't know how to use PS. Nevertheless, you cannot know PS perfectly, neither do I now, and I've got a lot more to learn :D
