My only (hopefully) constructive comment, Rick, is that while the HDR brings out fantastic details in the buildings, I find the skies to be way too over-structured. Same with the roads. The colors, and reds in particular, are a little too flat. Without having seen the actual buildings I wouldn't know, and perhaps the colors are very close to that, but if I saw these in a brochure I'd think them a tad too over-processed.
I'm thinking something more like this (my edit on the bottom)...
Changes are very subtle, but I find it more realistic.
