I think this one is pretty cool. It looks good and it's sort of cute and funny. But you mentioned this was for a competition, so I can't help but wonder who's judging/viewing the competition and if they might take offense to this.
One of the things I love about this image is that it's portraying the whole ritual as a bunch of superficial BS. Those aren't lovers or even people wining and dining. They're fake as hell, they're made out of plastic. You're sort of pointing out how fake and superficial that kind of stuff is, and that is REALLY a cool idea.
But I'm just saying...I can see some people not liking that.
