This is... wow. Honestly, I'm usually an articulate person and I don't think I can actually put what I really think about how awesome this is without the use of an expletive (which is a bad idea in devart comments).
A single look at this picture literally sets me off on a nerdgasm of amazement. I am utterly captivated by this piece, like, really. This is like, the sort of amazing multi-levelled industrial city-scape from all the best sci-fi fantasies I've ever had made real right in front of my eyes!
