You cannot tell in this picture but it's a Batman cup. So it has the buildings along the bottom, and then the spotlight and Batman symbol in the sky.
UPDATE: The clay cup is finished, fired for I believe it was two days, after being glazed. It has stars, building (which I originally thought would turn out this blue color, turns out Aquamarine its actually more teal... Or green) It also has the batman symbol which I'm quite proud of, considering I was hopping the yellow around it would be darker than the spotlight. Which it is.
