This is an enjoyable clay sculpture of Katz! I would give this a higher rating if you submitted the full sized sculpture, but I digress. You got the slenderness of his body just right, along with the shape of his face and his colors. One problem I see, though, is that his ears are unequal.
You are very talented at crafting clay sculptures, judging from this piece of art and your previous ones, so keep on improving!
