Robot Room Revisited

I photographed this room with a different camera a couple of months ago.
I'm convinced that there could be a photo somewherehere. This particular image may be as far as I can go but I won't know till I have a longer look at it. Sometimes just seeing it up as my screen saver helps me to make this decision.

The room itself already looks very interesting, just as it is. I wonder if I could improve the arrangement. It would not be as difficult as it looks. These shapes are made of wood. They are moulds used for casting gold digging machinery.
