I just have a character in my mind that I want to make, I decide gender, give them some random ass name I come up with, then just fill out the rest of the form how I want it. For the most part, I really suck at finding good pictures, so when I do, it's more luck than anything else. I prefer words over most anything else personally. So as far as a picture goes I decide a written description then look for a picture that matches or almost matches it. Things that typically aren't standard to a person are the only things that take a little bit of time to do. (EG: Magic.)
