This looks to be a compass sundial combination...

I love the render. Ironically I think that by making it the center of the picture and filling the image you reduce it to background as the eye looks for the center of what you've intended.


I think the highest goal would be to reflect something significant into the glass of the compass underneath the upper glass bits.

You might also widen the image to include something authentic and matte without a lot of detail. A contrasting item like a map or a canvas bag would be good - something mundane.

It would be brutishly difficult but very cool if you could make the render the subject of a drawing going on in the picture. That would be a render of a render in a rendering.

Failing that I like the idea of a pillar in white or a contrasting colour. If you could combine the rich metals with a rich marble it would pop!.
