What a beauty! Awesome variety of structures, yet with a common cityscape looking; quite an organic overall design! I love how you placed the color map too, very realistic but still giving much space to imagination
This is easily on par with any Sci-Fi future city I've ever seen. You can almost imagine it on such a place as Coruscant or Cybertron. Even the machine planet that VGER calls home. If I had the money, and it was available, I would want this hanging in my house.
