I did chose not to lighten the total image too much. Both from a lightness point of view as well as keeping the noise down. I really like @asn’s edit, but I do think it is too light (my taste/2c…). Going to have a look at his xmp now.
This is one I’m going to be playing with for a while. I think that the horse can be somewhat improved (both mask and white/lightness).
