black and white photos Metro in Washington DC

I thought this turned out to be an interesting perspective of the

metro ceiling :-) Thoughts and critism welcomed.....

very cool. i love these kinds of grand symmetries, well done!

First I really like this photo, especially the light. The texture of the ceiling is also very interesting.

One question though, why not give to this picture a little movement, why not a longer exposure time, so that you get the motion blur of the train. Why not give a little diagonal perspective to the image, it would be more dynamic.

Excellent work anyway!
