Subfloor is repaired...I think

I finally finished replacing sections of the subfloor. It was the most difficult task. I don't want to ever half to do it again. I guess that is what's keeping me in a bit of disbelief. Am I REALLY finished? Can I actually put the top floor on? What if I forgot something? What if I didn't do it right? I think I'm going to double-check, triple-check, quadruple-check it before I go any further.
