Hmm, I would have chosen slightly different approach. Did you use aWarpSharp() ? It makes the edges sharper, that's true, but also makes the whole image look a bit like painting if you see what I mean. On the other had it doesn't look too much like painting (I've seen a lot worse) so this is a minor complaint. This can sometimes happen, I've probably done it as well although I usually try to avoid warp sharpening. For this video I would have used regular sharpening (although regular sharpening and excessive denoise can also cause it). What more, although you did lower the reds, now in some places it appears more yellow-greeny than it probably should be (arm) and right side of Freddie's face almost turns grey. Also, the whole look is paler than the original (and I would have used some contrast as the original seems pale enough already). There is some chroma noise left (patchy colours) and chroma definitely needs to be shifted (common problem with old tapes).
So there's my two cents. Just don't get discouraged and keep up the good work :)
