I love this! Kind of reminds me of the Combine from Half Life oddly enough. In a way at least. When the Combine take over a place they place their structures into/over old buildings on earth. Like Nova Prospekt. A lot of the Combine buildings in Half Life are a mixture of old and new. The hybrid look of this, having the old city be covered up and transfused and buried by the new technologically superior city just kind of reminds me of that is all.
Looks like Blade Runner and Cyberpunk meets Deus Ex and Mass Effect. VERY nice work! SO much detail! Saved this to my wallpapers folder almost instantly.
