Having learnt a few new masking approaches I thought I would reprocess this data. I am now much happier with the overall image and can say I am glad to see the back end of the pinks. For those that are interested I used a straight RGB image then created a luminosity layer in photoshop at 40% opacity to get the image detail. Some otheer masks for the colour. It may be just a little on the green side for background colour, but not enough to warrant going over things again.
The only critique I would make is the green cast. No need to completely reprocess to remove it. Just preserve this version as a luminance layer on top and then add a curves or colour balance layer directly underneath it to reduce the green channel at the low to mid tone levels.
Thanks all, I have taken care of the green cast as much as possible without sacrificing the green channel. Marcus that is an interesting tip. Will keep that in mind for other projects too.
Marc I used that plug in. Works a treat. Thanks for the tip. I think you told me that once before too.
No worries - works well. You can kill all the green with it although there are different settings. I usually duplicate the layer on top then use color or lighten and opacity blend. Tweak until you like it. Doesn't work for everything though but for some DSOs it works great. Best one would be the HH.
There's a little green cast that you can get rid of with HLVG PS plugin very easily. See attached.
Don't ya like how Martin comes in right on cue too 
(not that he did it on purpose of course)
