Regarding the subsequent posts, I see an error in my ways. For white balance, I tend to just go with whatever the camera put into the metadata, but I can see now that decision renders a decidedly greenish tinge. I reprocessed with an additional “gray world” WB, then scooched the red multiplier up from that, and the colors look better. I’ll not post that render, as there are others above that have it nailed…

Nice, @iarga. I’ve come to the conclusion that colour is always going to be difficult with this capture because of the tint in the glass I was shooting through. One needs to compromise either by living with the green, or attempting to correct it and getting augmented pink/purple tones. As for grain, the compromise will remain between sharp details and noise.
Would you mind sharing the details of the colour filters that you applied?
I agree with you. My goal was going for a lot of (deliberately exaggerated) contrast and depth. The other renditions have a much more natural color. “My” tiger is more reddish and lacks the yellow and has a less pink nose (the yellow that makes a tiger a tyger 
). I didn’t want magenta/purple in the wood below the tiger. I used the G’MIC “Mixer [PCA]” filter and G’MIC “curves”. With the “Mixer [PCA]” filter I reduced the variability in magenta/blue-green/yello. Therefore less green, yellow and magenta, still there is some green behind the tiger. Then I balanced the result with curves.

The noise reduction of RawTherapee alters substantially the colors, so I left the noise.

This needs some proper music to go along with it.

I adjusted the raw black points first, to de-bias the green glass.
Local adjustment spot on the face for some increased light. Other spots used to shore up excess chroma which was distracting from the subject.

Edit: I see now I left some highlights on the right out of whack.
Thanks for sharing, Bill. To my eyes (and on my monitor) - each of which have their own biases - the tiger still has too much of a greenish cast.
I agree, Martin. I’m still trying to figure that out.
The Survivor music video shows that it is completely fine to have colour casts.
