He is plain looking. Actually, he looks quite friendly. Has a goofy/nice smile. He seems harmless.
You can see his picture in one of his older works, Undercover Cops.
A warning/blessing: It is not guro, but you can see some elements of what he likes, and Mai-chan acting as a clumsy henchwoman catgirl. Adorable and cute as always.
But Uziga SUCKS at normal comedy, sadly. Or maybe I don't get his humor at all.
