I really like this. I like the contrast in the colors, but I also like how you managed to keep the colors similar.. And I love how "clean" it looks. Great job.
This image really draws me in. The geometric figures make the image seem a lot more busy than it actually is. It makes me feel like I'm watching "Forbidden Planet" or something. Here'ssomething I think would make the image even better than it already is: Zoom it out and put a glass of beer or a martini next to the structure. that would soften the feeling that the viewer gets when seeing the gestault. Don't take this as criticism though - I like the image.
