Your scroll work is great, my initial thought of the pieces as a whole was, I like it but its missing something, it's a bit difficult to pick up on the layering, maybe staining one or two of the pieces will help make the layers pop. I really like the concept and it has lots of potential. But then again, maybe the layers just don't show that well in the pictures. I hope to one day be as skilled on the scroll saw as you are, you're fret work is beautiful.
