I loved the idea of this advert when watching live, but have one question. Who is the target? And who is the "we" the card is from? (Ok. That's two) I have a bunch of other questions as well, but they may not mean much without knowing the target audience. Also, might I recommend that he also take photos with a dark (black/wine) colored bra to see what that looks like. A light colored bra might distract from the card and a dark bra would bring the focus back to the card and be more of a surprise than a focal point, IMHO. Sometime subtly speaks louder. My 2 cents without being asked :). Finally, I do hope we get to see the final product.

what about this: left foe ground very close 30% of the shot with better more white yellow light on a round white clothed table, half full wine glasses, background moderately out of focus fire side and naked couple silhouette (lower lighting and soft focus hiding details). You would need f3+ to control background blur and balance it against low light.

you should put red cordial in the glass, it will show up better under low light. Also some women prefer Champagne
