Hey Michael, some suggestions:
Re #8
Great shot! …just brighten it +5-10, and + 10-15 saturation.
Otherwise very cool!

I dig this take! It's only flaw, IMO, the highlight area at the bottom right.
I'm sure you can take it down to match proximities.
Re #73
The shot is fine… the shadows are too harsh. Use a Rogue diffuser!
Have a good day…
