Hi Les, I was picking up as Ed, what looked the gloss interior of the bowl, but in the second shot looking over the rim it's not noticed, if it had been so (glossy) it would make a nice contrast detail.
You've one wonderful form, in part due to the walnut, and the lines which do lift the piece an set it off really well.
You've become a bit of a master with your turning, as well as in design.
Cheers Dewi
