Very nice on that face shot! ; I have simply not had any luck at all getting that one. ; I tried this weekend, but didn't nail the focus on the side shot, and didn't time any of the lights for the second. ; And I never seem to get lucky with sitting on the correct side of the boat.
All nice shots throughout - I'm still sort of torn on the white balance issue - though correcting white balance is pretty necessary as it will severely blow out reds and yellows, I find I prefer to leave some color cast in and not go for 100% accurate WB...since your eyes are seeing color cast when you go through the ride and I tend to like to capture it as it's seen. ; I see some nice shots that have been fully color corrected, and some nice shots that haven't...neither is right or wrong, but I tend to lean towards the slight color cast shots. ; Yours have some light color cast still there in a few, which I tend to like.
BTW on noise removal, have you tried Denoise5? ; With lower ISOs and lighter noise, I think many of them are pretty close to even - but when it comes to extremely high ISO and heavier noise, I find it just does much better than any others I've seen.
