I agree, I’m digging this one.
My only suggestion, and it’s an odd one, is maybe to do a separate grade for the scenes that show the surface of Crait. The dark, rich, deep reds that spray up in contrast to the pale white are such a great visual, and literally the only downside to this grade is that it mutes them a bit. Other than that, I think this one looks good across the board.
Since I’m aiming for a cinematic looking grade, the desaturation is intentional. I have faith that the reds on Crait will look rich enough since the viewer will have already been adjusted to the grade by that point.
Check out the movie Three Colours: Red by Krzysztof Kieslowski - you might be able to do some colour analysis on it and really amp up both the reds and the filmic look on Crait and in Snoke’s throne room (though I like your grade on Snoke’s throne room). It’s shot on 35mm and (as you might imagine) it extensively uses all different types of the colour red throughout.
