Thanks for all your thoughts!

@jerryshadoe: you want to drive me crazy, eh? (-^,) I may agree with you but I'd like to apply just one kind of setting for the whole movie because, at the contrary of "some" movies (you know which ones), this, apart the obvious pink blanket, has not a so wrong color grading... it is watchable - after the obliged contrast fix - "as is", and albeit too warm IMHO, doesn't look wrong... well, here you are the OLD/NEW compared:

to tell the truth, I still like a bit more the OLD settings... examples:

#1 - OLD has the snow almost white, even if a bit blueish, but it's OK, as in reality polar ice tend to seems blue, while in the NEW it's a bit too pinkish

#2 - the skirt in NEW seems also violet, while in OLD is almost blue, and I'm pretty sure Charlie will punch anyone in the face if he will ask to wear a pseudo-violet skirt... (^^u)

#3 - take a look at the street color "homogeneity", in particular behind the dog and under the man; those parts have not a consistant color in comparison to the rest of the street in NEW, at the contrary of the OLD - or, maybe, this is due to the fact the old man is doing a random cleaning, and those parts are still full of dirt... (^^,)

About grain: this was my first attempt to regrain a movie, and I'm happy with the result - like you are with LOTM, aren't you? Of course, original grain would have been better but added REAL grain is better than added FAKE grain, and surely better than almost no grain at all...
