Carving the Tops, Take 3 at Least

All this year I've been trying variations on carving irregularities into the tops of bowls and vases. Here are the latest versions.

 I am learning that it works better on pots with certain proportions: relatively narrow tops or something I haven't figured out yet. I like these vases. I think I like the bottom one best, the rounded shape and the complicated carving. 

These are glazed only on the inside. The more interesting the clay, the better they work. Or do the variations in the clay color (mix different colored clays), and the horizontal lines from the clay moving on the wheel actually distract from the emphasized top rim?

Perhaps they look better, taller. I'll try that next. How marvelous that there is no end to possibility and learning.
