Nice shot Raj - I love the look of the dark almost menacing sky. The architecture is gorgeous too and I like your crop. Leaving a bit of wall along the bottom edge of the image adds a definite boundary to the building. I think the square crop works well, although there is just a touch too much sky for my taste.
You seem to have gone for a dark and moody look here, but in doing so, some of the fine details of the building that is not being hit by the sunlight are a bit more subdued to the point where they get lost. I would be tempted to burn in some of the building details just to bring them out a bit more.
This is sort of what I was thinking about
:
I wonder if I might see it myself later on this week when we spend a couple of days in Delhi. The location does not look to far from where we will be staying.
