Thanks Phillip for your images and this opportunity to comment.
I like the crop version on 1. It has a much stronger geometrical statement. The original version is quite striking and has an element of depth and dimensionality - which when cropped is removed , however, I think a much stronger two dimensional geometrical image results by cropping.
I also like the B&W version of 3. Is there any possibility reworking it a bit and having more tonal variation in the dark areas? It just seems a bit heavy, and perhaps it may be more interesting if there was a greater tonal range across the darker areas.
I think your lobby view (link) reminds me of an advertisement for a motel. It doesn't do anything for me, but that is totally irrelevant, because if you are happy with it and like it, really - that is the only thing that matters.
