Overall an interesting piece, I too, like Bob was unsure of the foot at first, but looking closely I am not even sure it is a foot, is it some sort of coaster that the bowl is standing on? It looks slightly off center and of a different material, like a marble or something.
If it is a foot, then I actually like it, it's unusual, and crisp too.
While the wing is an interesting "bit" I am not convinced it actually adds anything, if it were highly figured like the rest of the bowl it might have been better, but it looks rather odd and somewhat plain in comparison. Excellent turning work and nicely finished too.
