Some of the grading goes too far in my opinion, for example making mauls black cloak look green. But I like how you got rid of the purple. Very strange choice for Lucasfilm.
See, I’m not really seeing green. Maybe that has to do with the settings on my monitor, but if there’s green to that cloak, it certainly presents a problem, as I didn’t do any green level adjustments in that scene.
…though I did use a slight teal filter to neutralize some other colors. That may have done it. I’ll give it another look.
One way to check your work is in Photoshop, where you can get RGB info for any pixel. It’s showing higher green levels for the shadows than the other colors.
