@Sarahmaeliz Yeah if you sat them on the bench you'd have to change the composition completely. They seem happy where they are anyway!
It certainly feels like a communal area, it has a nice cosy wintery feel to it. The main couple do feel a bit like they're done in a different style though, as they have an outline but nothing else does. Unless that's intentional of course. If you look at the delicately painted background, the warm glow of the people on the bench, then look at the couple. I think they would look so much better without that outline.
