Yes, for those panels I used a large ambient value to make them cast light
in the radiosity step - completely pointless as I realise now, because
there's very little geometry facing them. I should have dialed it down in
the second pass but didn't. I've now fixed that. Not too sure about light
fading - I think the "unreal" flavour in the first image is mainly
contributed by the extreme flatness of the radiosity, and I don't want to
weaken the (area_light) sun too much.

The people are meshes of about 700 hundred polygons each. I've tried to keep
them back from the camera, but I wanted something to add scale and break
the symmetry a bit.
