Doesn't look quite right to me eyes, on my monitor
I obviously can't comment on your monitor, Bill, but it looks OK (by that I mean realistic) on both of my twin Dell Ultrasharp U2711 screens calibrated with Spyder4 Pro. Maybe you are thinking that the green ferns on the rockfaces are a bit over-saturated but that is how they look in July in Scotland.
For what it may (or may not) be worth, exposure details are:
Nikkor 70-200mm f/2.8 lens at 135mm
1/100 at f/14, ISO 200
Lee 0.6 ND soft grad set high in frame and angled anti-clockwise
