[@PrettyWings] As long as it looks like a person. Realistically. I'm not looking for anime or angels or demons or what not. If you really cannot find a picture you don't need one, as long as you are detailed with your description. Sometimes a well-written description is better than a picture in my opinion. The only advantage of a picture is that humans learn better through sight and visual aids such as pictures help that. 

Is that answer enough? 

Bottom line, pick a human looking person. All I'm looking for. If I could imagine in my head that a person who looked like that could walk down the street of earth, you're fine. You don't even need a picture.
