Hi Les, It's never easy to make a call on a picture of a piece, you've done remarkably well with the form of the pot, for me the lid maybe a little predominant in size and for the Walnut, the flow to the pot, could lead into a lower lid and more of a detailed knob, than going for a finial, then without a feel for the piece, it's difficult to judge, I like the idea with the piece.
Cheers Dewi
