Sorry Peter, notwithstanding the wonderful lum data, the colours miss the mark for me I'm afraid. Too bi-colour (magenta and cyan). And where's the green? Have you deliberately subdued it? Removing some magenta and bumping up the yellows would be a good start to making the colours richer. (I was able to get a
much warmer & richer result with selective colour, curves, saturation and vibrance layers & ten minutes of fiddling
).
