My first thought was that it was too blue, but after looking at the '04 version again, I hardly think so, as it's nowhere near that extreme, and being completely white is not right either. Seems like it's in the right vicinity colour-wise.

You might want to consider bringing the white level down for this scene and some of the subsequent shots of Luke lost in the snow. With the blue levels in the '04 being out of control, the over-brightness of the image isn't obvious; but once the colours get back where they should be, it's easier to see (even more so in adywan's version since he reduced the blue more than you did). Of course we all know the GOUT is hardly an ideal reference, but the snow scenes aren't nearly so bright in that. And Han does say it's getting dark out there, after all. ;)
