Akira,
I appreciate the effort, but wonder exactly when these photos were taken in relation to the time of sunset? I was taught that the 15 minute period after the actual sunset had sufficient light to see detail in the surroundings while still allowing one to capture the beauty in the sky. In my opinion, all your shots seem to have been taken too late resulting in virtually no detail in the buildings.

Robert, thank you for your comment. I understand what you say, especially considering your photographic style which I always appreciate.
As Jack fittingly points out, I wanted to keep the details of the buildings as only suggestive as possible. Also, I wanted to utilize various reflections and light sources as compositional elements. I believe the same applies to the image posted by Jack here.
And, as Paco says, that is intentional and is my favored way for the abstraction.
Although I initiated the thread in this category, rendering the details of the buildings clearly was not the purpose for the images. In this sense, my images may not be considered as cityscapes as documentations of the scene.
As a believer of the simplicity, I always go for the beauty of ellipsis, and I found the underexposure of the shadows works well for me.
