The one’s matched to the the French trailer and the telecine look good in my opinion, but fix the black crush on the regrades, don’t darken the skies, it’s blocking the stars. The Blue-purple tint really transforms the image. It creates the feeling of the icy cold waters of the atlantic, which is gone in the BD.
Also, I would advise you to turn up the contrast in the night scenes for the telecine regrades as the blacks are looking grey on those. The Film cell regrades are blown-out, don’t use those.
Finally, a photochemical timing and 35mm projection colours cannot really be recreated on digital intermediate sourced blu-ray which was digitally graded. We need a 35mm print to get close to that visual aesthetic. The Blu-ray, though quite beautiful, has a new colour grade. It looks too proper to give that imperfect but organic look of the prints. But still, good work, keep it up!
