Mike, there was another, smaller circular base under, enabling the upper to rotate. The client didn’t want that visible and I agreed. The lower base was made of glass, thus allowing the light behind it to shine through really bright, just under the darker upper tray. Having the brightest part of the image at the very bottom, when the attention should be on the flowers above, wouldn’t be the brightest idea, pardon the pun. I was initially concerned it would make the overall composition a bit cramped, but I think it worked rather well in the end.
