You've heard the expression ' a picture is a thousand words '. It has never been more true in art. Art speaks. Through drawing or painting one expresses one's thoughts, beliefs, preferences and character. For example if an artist paints ghosts, it goes without saying that the artist believes or at least entertains the possibility of an afterlife. An artist who paints beautiful women is showing he loves the ladies. One who paints churches is a believer. One who paints landscapes loves the outdoors and one who paints animals loves or respects them. The list goes on.
How it's painted tells more character. There are neat and fussy artists and there are messy ones and thousands in between. The way in which the paint is applied shows this character. Like handwriting you can't escape displaying who you are in a painting.
There are exceptions. Commissioned work is for the client and often the artist's character is not as visible as it might be. Some call commissioned work glorified drafting. I'm not sure I would go that far, but you get what I mean.
