Technical skill does not create art. There are many people who are technically proficient at various things who are not artists.
The other side of that coin is that art is objective, and not everyone will see/hear/feel the same things based on the same work. As the old saying goes "I don't know anything about art, but I know what I like". That said there are many 'great' photographs that are not necessarily 'art'. PJ's for example dont have to create art to create powerfully moving images, but it doesn't hurt. There are also great artistic photographs that technically are 'eh?' if you dont know what you are looking at. Some of my favorite examples are from cartier-bresson's work. He was very much about capturing the moment. If he were shooting now 'That's not sharp, its out of focus, Get an L, your rangefinder sux!' would probably be most of the critique comments, never mind the work!
I figured out a long time ago my right and left hemispheres clash and the result is what is inside my head rarely makes it out via any medium, but photography is as close as I seem to be able to get so I'm sticking with it (what are hobbies for anyway!). I'm still working on technical proficiency (lighting has become the bane of my existence when I have the time to complain about it) , but every once in a while I shoot a real winner that other people ooh and aah over, so I must be getting somewhere.
And yeah, the muse. Evil evil muse. Sometimes the best thing you can do is stop doing something for a while, and wait for inspiration to hit anew.
