An interesting subject. It looks very difficult to illuminate to catch all the nuances. I hope you continue to try to capture the elusive delicacy of it. The harsh light under the plate distracts, I'd suggest a tighter crop there. Shoot this in natural light, it cries for another shoot.
the exposure on this image seems a little flat... i also think that a different angle that added some depth dimension to this photo would make it stronger also... - setzler
A shot of strictly Other Peoples Art, and you really don't do anything to enhance the shot. Why is this a good photograph? What does it make us feel? It would be a good shot for a book on this type of subject.
