Obscured

I usually don't like photos of the sky because, more often than not, sky photos are pretty damn boring. Yesterday, however, I was walking around downtown (the Hudson River near the Holland Tunnel to be exact) and I thought this looked pretty cool. Granted, it needed a little Photoshop help. I tinkered with the RGB and Red channels in Curves and then a little with Brightness/Contrast, but neither alteration was very drastic. So tell me what you think!
