Paulista Avenue

This one is almost a no brainer. A near perfect HDR pano, especially because the tonemapping is nice and subtle. The spot you chose is amazing, quite a unique angle on a city street. Impressive work overall. My only two cents would be that it looks a bit crooked here and there, there's no clear "horizon" or curving, or at least it seems a little of to me. Other than that, a little more traffic below would have been great - the streaks of red rearlights would add a great finishing touch. But alas, that is not under your control.
