3 stop ND graduated filter used to balance the exposure between the sky

and the buildings. Thank you

I first thought this was 2 images joined at the center. The sky seems like 2 different skies. The cloning work on the large cloud just left of center is a little obvious. Maybe that is your intention. It certainly makes me stop and consider this longer.

It was actually 6 images put together. The only cloning I did was on the top left because I cropped it little too much. Thank you for looking and your comment.

Maybe what I am seeing is a product of the combination of images. If you look at the large cloud, the shadows and forms are duplicated in the center and top third.

yes it does look odd. It's probably like you said a side effect of multiple images being stiched together.
