very interesting composition. like the colors, lines, and angles. as for the challenge, i don't know if you'll lose out of the international voters who may be unfamiliar with the mayo's.
Hmmm... is that a hospital.... is MAYO an acronym for something ?? Otherwise I'm not really getting the challenge link here. I'll give you the benefit of the doubt and a 6 for an interesting perspective.
Nice use of line and contrast of line. The shiny clean image certainly match the image of the Mayo clinic I have in my mind's eye. The brilliant blue sky and the shiny metal work so well together. It is rather dizzying, though, which counters the idea of stability I have when I think of the Mayo Clinic. It does give a sense of limitless possibility, so I guess it does work well. I just to have to step back and let go of my preconceived ideas. Nice photo.
The converging lines of the building probably would have been interesting enough without the angle of the frame. It's a bit of a shame in an otherwise good shot the reflection on the "M" is so bright an over-exposed.
