I'm an occasional editor who works mostly in the art sections, although I sometimes stop by deletion requests.
My favorite art types are realistic landscapes, such as those found in the Hudson River School, but I also like pictures of people having fun. As the saying goes, "Take your fun where and when you can, because the ride gets rocky way too often."

I'm sure there are a great many other wonderful artists out there. If you find another similar to those listed above (not in the Hudson River School; I know all of those), please tell me.
