Mayank, I agree - that one young man who has turned his head to look does make this photo sing. Your black and white treatment and the degree of "zones" that you've achieved also really enhances the image. The whites of that man's eyes, those couple of white shirt collars, the white design on the back of the dark jacket on the lower left - and the patterns of what we can glimpse through the temple's door all work so beautifully together. These highlights help draw me, along with the devout, through the doorway. I feel as though I am being carried along in the throng.
I don't know the camera you used, but I am very impressed by the way you were able to use the zoom to reach across the road for this photo. You and your camera worked really well together!
