Cedric,
The reflection in the building is interesting. Maybe this could be brightened to balance the picture more and then it might explode with power. It obviously has considerable potential and is a great choice. This is an impressive architectural space but a challenge to do exceptionally well. There are no people or human images or words so your usual style does not translate easily. So here I don't see you own fingerprints. Here's my idea. Just an idea. Try working on it, perhaps, to to distribute importance to parts as your mind values each part. This can be done by very, very slight blurring, sharpening, lighting and contrast differences.
If you might do this, then he image is just at its early stages. Still this an unusual set of shapes and the rust like colors of the curved staircase wall adds something special. However, perhaps, this project is not yet finished?
Is this near you?
