Les, I've been looking at this for over a day now, wondering what to say, well here goes...
The smooth flowing curve from rim, via the foot back to the rim is one long smooth shape, almost a perfect parabola, a simple shape but far from a simple thing to get right when turning.
It would look special on any turned item but the spalted holly timber (yes we are all still jealous) is just stunning.
You've turned something special in this, be very proud of it.
