That is a very very interesting picture, because it's so confounding (to me anyway). On one hand, it is tempting to just pass your eyes over it and then think that it's just a seemingly random architecture shot....
But the more I look at it, the better it looks! You have some very subtle light gradations and some really delicious hues of blue and gray. The slats and colonnades and tiled floor..makes the space look both high-tech and old/classic at the same time. It's like it was taken right out of the officers' deck on the Death Star!
I think you did a fantastic job, taking what is really a high-contrast scene and retaining lighting on all the features of the space. It's very "moody"...rich with ambiance really...and the more I look at it, the more I want to look at it.
In short: I really like this image and your treatment of it!!
