ok i know what post you are talking about and the writer had a point. however what he was seeing was the ear was too thick and had an unnatural curve to the ear that more so went down. the ear should be thin and have a slight bend or "flair" to it. some people put a noticeable flair to it more so to the tips and that is ok to. just follow your reff pics and what looks natural to you.
I think he was referring to the post " # 5"
