I wasn't sure what I was looking at. Had to get my wife here to point out that they are chairs (They are chairs right?). Definitely meets the challenge, but it's kind of boring. Nice try though! 5 from me.
Oh man! This reminds me of college graduation at a large university. How funny, but amazing, at the same time. I like the lighting on the one row of chairs in the middle. It helps my eyes focus so I know what I'm looking at.
A single person on one of the thirds intercessions would have lifted this tremendously, although I suppose it could be argued that it would damage the symmetry.
