Pete,
sorry these don't work for me an any way. The cup section is not a smooth enough flow from lip to base. The base (certainly on the larger one) does not sit tight to the cup, it's neither a stem or a good joint. They have torn grain showing inside the cups and the final shapes and finish on the finials is lacking.
Having said that, I love the idea of making this sort of branchwood box and can see that there is great scope for them.
