There are probably more changes to come but here is where I am at.
I have gone with three versions. This may be overkill but they all look quite different when installed and there are good reasons for people to have different preferences.
Not everyone will have Kursk, but if you have, installing and comparing these will give you a better feel for the strengths and weaknesses of each versions. My screenshots do not tell the full story. I recommend using JSGME if you intend to do comparisons.
The Russian Guards now have more red, as The_General suggested. But as I said before, to some extent the colour washes out as the sharpness increases.
I will carry on applying this approach to other titles but any comments are appreciated.
