(1) COMPOSITION (CONTENT) I find the layout of this photograph to be very strong. The spiral of color and the off center placement of the center of it all add to the power of this composition. I am so glad you did not center this, that would have made it into a bullseye.
(2) BACKGROUND The background is very dark, which make the bright colors of the windows really "pop". Perfect background exposure.
(3) CAMERA WORK ,TECHNICAL The focus seems just a trifle soft on the windows. Did you hand hold the camera at 1/30? Did you try this with a tripod? I think just that little change might have moved this into ribbon contention. You also might try this shot with a smaller aperture. That would add to the DoF and more of the windows would be in sharp focus.
(4) DIGITAL PROCESSING ,TECHNICAL Your post processing is very good. Saturation is good, cropping is perfect.
(5)MEETING THE CHALLENGE This photo does a very good job of meeting the challenge. I love the colors and the feeling of movement from the spiral.
(6) MY OPINION ON THE PHOTO The subject here is fantastic. The way you executed it is excellent. There is much to see here and this is the sort of photograph that can hold my attention for a long time. This is a wonderful photograph!
I love these spiral shots. The only minor thing I might want to change is to darken up that glow just a little, which I know was likely difficult due to the setting of the shot.
Where is this I would like to visit it some day? The lights at the top are a little distracting but that can't be helped, I also like the way you off-centered the pic. this is far more pleasing than dead center. The old rule of thirds comes into play again. The architecture and color make the image, Good shot and good luck. John Gill
I almost submitted this same shot! Glad I switched at the 11th hour! Had fun shooting on Saturday, guess we need to discuss what we're submitting so this doesn't happen again.
That being said, nice shot, a little dark and might stand a bit of a unmask sharpen. I like your composition.
