Wonderful! Perfect compostion and color. A tad too much pixelation though.

What, no girders and windows? ;)

Interesting and original.

Looks like a Space Station... I like the Depth of Field.

I like this. It's unusual. For me, impact & composition are both above average. But I find it suffers in relevance. While there is certainly an interesting repetitive pattern, I don't see "geometry," which I tend to think of as lines, triangles, squares, rectangles, circles, etc. I hope that makes sense, and that I haven't misconstrued geometry!
