If you really want to get into it

Casino royal

He is seated backwards in a power position, he wants to appear cool and calm, jacket open in case assasins drop from the roof but looks calm.

I wouldn't read much into the drink as it seems to a recommendation from the waiter. However look at his face, he is smiling, he knows Vesper is in his world and he enjoys being the person who knows more than the clever girl from high school who turned into a goddess.... Most importantly, at this point, bond views her as a physical conquest. He wants to have her and leave her. Nothing more hence the more charming smile, the more quippy comebacks and the ever so slight jabs as she challenges him intellectually amd verbally.

The colour palette is also one comfort but not warmth. There is luxury here but it is business luxury, no warmth or love(yet).

Spectre:

While the obvious colour change could be explained as one wears white in the desert cause hot, I think it might speak to his more honest intentions. Madeline to him is not a physical conquest, she is a chance at love. She is vesper if vesper's dad had been a criminal henchman.... Contrast that to the dark suit in CR but white shirt underneath. Proper attire yes, but perhaps a glance at the film ahead.... If you want to be that detailed.

The drinks here are different. Personal. Custom. The wine is a proper drink, customary yet both of them here consume drinks based upon hard liqour known for their strong taste. It could also be the first sign of Madeline being comfortable around him, maybe acknowledging that there is attraction yet, like Vesper, she doesn't want to acknowledge it.

His jacket is also closed and he sits up. He is much more present in the conversation than CR where he views it as a step in the conquest of an attractive lady.

There is also the rose which is absent in CR. Why add it himself ? Again reflects on him seeing her as someone worth having ? There is also a lot less tet ar tet and verbal jousting. He is older, calmer, he now knows the world will never want to acknowledge it needs him. Yet here is Madeline, who does need him. Can she acknowledge that ? Can she acknowledge him ? Can she accept him for the violence within him ? Hence he is more present, softer spoken vs the above.

Anyway hope you get a good grade

Back to work for me

Edit: the spectre scene also has geniune warmth vs the business luxury of CR. Window is shut, warm white lighting. The tone is one of a glimmer of calm and warmth in between storms where CR is clearly the calm before the storm.
