When you refer to your image "Playa Reflections #1", you say that you thought you'd gone too far in terms of creativity. What does that mean? Is it really possible to go "too far" when it comes to creativity. (I'd guess so, although a good example of the concept doesn't immediately come to mind.)
Your final decision on whether or not an image is too creative seems to stem from its market acceptance, rather than your own feelings, because you state that both of the playa reflections images have become best sellers. Is that the only way to determine the limits of creativity for an image (or anything else, for that matter)?
I understood "gone too far" as meaning "trying too hard", i.e., thinking so much about how to be new and different that the final result looks contrived. I agree with Alain that it didn't come out that way, but I see a fair amount of modern art (including some photography) that ends up that way. I like art to be something that asks questions or tells a story, but I'm mighty tired of the only question being "Is this art?".
