Awesome. The colour and the way it looked like a cityscape from above at first (to me anyway!) reminded me of a scene from the Matrix. I like this because it can be interpreted in so many ways to be so many things. Well done!
Nice render. What the marked things are suposed to be? I would make them different from one another. Cloned part of a drawing always keep my attention. Unless they´re really suposed to be cloned... inb that case nevermind. Great art piece!
