Okay, as I'm quite unfamiliar with these
particular series, I couldn't answer his question
myself.  I'm betting you guys can, though.  ^_^

Are the following series cel animated, or
digitally colored?

A.D. Police
Bubblegum Crisis: Tokyo 2040
Sorcerer on the Rocks
Ushio & Tora

Any help would be greatly appreciated, thanks!
