Really nicely shaped bowl, and the lip detail is outstanding as is the bead underneath, itself echoed at the join to the base. The exquisite detail on the base need also be mentioned.
Were you to try to make a copy of this goblet one day, or another like it, would you consider turning the stem a bit more slender, maybe trim the height (thickness) of the base to about half, and alter its diameter somewhat?
It goes without saying that tastes vary from person to person, Just an idea or two. Congrats!
