These ominous clouds were hard to pass up. What also made this composition compelling for me was the great arrangement of street light poles at the bottom of the frame.
One final thing, the John Hancock tower, looming to the right of the big light pole in the middle, came out in a weird shade of light green when the color image was taken. The need to decrease the emphasis on this distraction was a big reason why I switched to printing this in black and white.
Hope you have a great weekend.
