A lot of architecture shots don't look all that interesting to me as negatives, but this one really does. Great composition and I like the tones and patterns.
At first glance this was my favorite and now having looked through them all and really examining the different approaches people took, it's still my favorite. The colors and exactness really give this a graphic design feel to it, like a precision-made futuristic cartoon. I also was going for this look but missed the mark. The scene is well spotted, but the colors and shades really put this at the top. Well done.
