Just cuz one drawing looks more like a human than another drawing doesn't mean it has a better likeness. This is an obvious truth to a caricature artist. When we are very young and learning to draw we will attempt a likeness, but if we fall short, we take consolation if the drawing is recognized as being of a person, but now, as caricature artists, we find the system completely reversed. I think the ultimate ideal caricature is one where no semblance of humanness remains, but still the likeness is there. This is not that drawing, but it is a drawing I am very happy with. It is of my friend, Eric Goodwin. He recently moved to San Diego. Wazup, Eric.
It is quite possible to copy a photo of a person as directly as you can and not get a good likeness. This drawing of Dave Chappelle illustrates this. It's not to say that a portrait is less prone to capturing likeness, but for a likeness to be caught it requires the same amount of attention that a caricature requires. It demands the sensitivity of a cautious and judgmental eye.
