I work only to please myself - photographically, at least.
But my "acid test" is whether my pictures also please my wife! If they do, they are ready for a wider audience - like the APUG galleries and print exchanges. Thinking about styles, influences and so on will only lead to "cramped" pictures. I do the best work when I only work from the "hm - that looks nice" principle.
In a way it's similar to my other form of artistic expression: I'm a singer. I don't sing rock, and rarely jazz. Am I any less (or more) of a singer because I'm classically trained and sing classical music?
