OP's photo 1 and 2 are awesome!
Here's proof that FF can also take bad photos:
5D Mark II @ ISO 25600

This was one of my first shots with the 5D MK III and 70-200mm, when I was testing the body out.
This was taken in near darkness at f2.8, 12,800 and 1/15. I was impressed with the AF speed as well. Yes I know both eyes not in focus etc, but impressive ISO performance, no?
