This is amazing, wow! Yes, there are a couple of frames where the face isn't hers, but that's understandable since the original has almost no detail. Still, everything else is just wow, so incredibly detailed. My only note is that I wouldn't use such high sharpness settings. Britney's music videos were shot on film, so they should have a slightly softer look, while still remaining detailed. I hope you’ll have the time to do equally detailed restorations for all of Britney’s music videos, as not everything in the previous releases is perfect.
