not too bad. captured the moment pretty well. the dance looked pretty dark and it looked like you had your ISO cranked but it also looks like the only light for that was those little lasers so not much you can do about that. maybe try grading the footage a little more and watch the exposure on a couple of those ones with the sky.
overall not too bad, my grandparents last name is Keller and i kept thinking i would see like a flashback of a wedding from like 50-60 years ago haha
