Hey, You went out photographing, and that's far better than staying home and not photographing. As far as your mistakes, I'm perfectly capable of making those mistakes in warm, calm weather during the day. I was out Christmas afternoon and evening with a new Speed Graphic, had all kinds of fun, no major mistakes that I know of, but I know more after I process the film this afternoon.
Good luck with your color negs, maybe the lab can pull process to compensate for the over exposure. Don't know as I shoot mainly B&W. I would certainly let them know that the negs. are over exposed. My other thought is that depending on the reciprocity failure of your film and the length of the exposure maybe the negatives aren't as over exposed as you think.
