OK, here’s my take on your regrade:

I like the warmer skintone on Leia’s face but I think the walls should be cream-coloured and not pinkish
The frame of Ozzil, Vries and Piett looks fine save for the actors faces which are too pink for my liking, almost as they’re all blushing. Maybe balance it out with a touch of yellow/orange and their faces would look fine.
While it has been agreed that Hoth is blue, the blu-ray went overboard with its blanket blue/cyan tint all over the movie, which is most apparent in the Hoth and Dagobah scenes.That being said the AT-AT and the snow now have a hint of pink.
That frame of Luke looks better but I suspect it should be a bit more grey-looking and Luke’s pilot jumpsuit looks a bit red instead of vivid orange.
Absolutely perfect regrade. Now Yoda is back to his natural olive green skin colour instead of the neon green that almost makes it look like he could glow in the dark, and the surrounding enviroment is back to the muted greys and browns I remember from promo shots and colour-corrected Grindhouse.
Actually this is the one where I think the blu-ray looks better. Your regrade looks a bit flat.
Another massive improvement on the blu-ray with the added bonus of restoring Vader’s lightsaber core to its original white instead of bubblegum pink.
The light beige on the walls of that frame is how it’s supposed to look, plus the overall warmer tone is a lot more pleasing.
Again, the warmer colours are a lot more pleasing to the eye and 3PO looks more golden which I like a lot.
This is yet another improvement with warmer colours. Notice than in the original blu-ray screenshot 3PO looks almost silver.

Colour-wise it looks better save for overly pink skintones on the Imperial officers in the second set of frames, but in terms of overall image quality I consider TESB to be the worst-looking of the OT blu-rays.
