I like the idea, and the execution so far. All the previous suggestions have a lot of merit - especially those of taking away the "extra" chairs, and turning the remaining two away from one another. My thought on something to add would be a document on one side of the table, with the title "Divorce Decree" (or whatever divorce papers might say at the top), then a bunch of legaleese (which you probably wouldn't be able to read, but would be there) then two signature lines - one signed, the other blank, perhaps an uncapped pen lying on the paper. Might be too ... official? Direct? Another thought is, since you don't want actual people in the scene, to make the shadow of two people talking, either fighting or working it out, cast on the floor. My thoughts, anyhoo. Nice work so far. Look forward to seeing the final.
