I like the layers, sort of a combination of fretwork and instaria. There was an article in one of the magazines a while back that discussed carving fretwork. It is an interesting idea.
since you asked for opinions, I think the ledge is a little bold in the tiger pattern. My attention is drawn to the ledge and I was trying to figure out what it was. If it wasn't such a bold, beautiful piece of wood, it would be easier to see the tiger.
These are really awesome pieces, You should continue to explore the idea.
