5 made me gasp.
I'd like to 3 in mono, I think it would have a little more impact.
Any chance of lining up the crop of 2b to correct the slight tilt? Also, b looks like it has a little more contrast than a.
There are people in 5! LMAO - I didn't even see them either. AWESOMEness! I love 6 but I can't understand it. Is that the sky above them? Are they sitting in the stands?
However fake-TS fail on #5 (and boo to you for stripping EXIF ). I would've dodged/burned to have the couple stand out via light/dark contrast instead of the more-nervous-to-my-eye focus-contrast. A novel photo due to your access, something other 'togs will be hard pressed to recreate.
How do you get into these places? Is it your client (like the SWA shoot)?
EDIT: just read your wedding thread, and I guess you have a honest-to-goodness T/S lens. My bad. But I still would've shot #5 straight up and used lighting to contrast.... YMMV.
Tight portraits are nice but 5 is one of those shots that could easily be blown up to some ridiculous size and hung on your wall without looking like you love yourself.
