I think having your own "critical lens" in which you view your own photography is probably a good thing, but it is important to remember that good photography is not necessarily art nor art necessarily represented by good technical photography. Photography is truly about imagery and the emotion that it provokes in the different individual viewers. In short, one person's art is another person's junk.
Once you know the basic rules of photography, feel free to break them. The famous artist Salvador Dali, could paint photo like representations of about anything. He chose another path and that has made all the difference.
I recently posted a shot to a photography web site that I almost didn't post. The curators saw it and made it a featured shot. It was flawed in my mind, but they felt the imagery overcame these flaws. The great thing about photography is that no one shot is truly perfect. This statement does not hold true when you look upon it as art. So think of your photography as art, an image to be conveyed, a moment captured, time in a bottle but keep that critical lens.
Last analogy,
There is no perfect shot like there is no perfect wave, we are always paddling out farther for the next one.
