When you get to the point of aging the body, they will ask you to take a look at existing pics on their site and pick a few out that most closely represents the aging you're looking for. IMO explaining the specifics of aging is alright, but far more difficult to get than pics. I would suggest finding specific pics you like (whether it's on their site or elsewhere) and send those to them. When they did my aging (see above), I mentioned that I wanted medium aging and something that looks like it's been legitimately on the road for the past 20+ years. I think they did a super job with it!
