I would second Chip on the issue of giving the figures enough detail with that viewpoint. I would recommend that you have take a bunch of photos of someone in a similar setup to get a feel of what would work best. Your viewpoint will be very dependent on what the story is that you are going to tell. Is the person setting up the scene very important? If not, it might be good to have an over the shoulder shot, indicating that there is someone making the scene, but putting all the energy of the scene into the figures themselves.
