Some of us aren't very talented in textures, etc., but we have pictures that we want to create. My talents are in writing, (at least, I hope I have writing talent!) but I have scenes in my mind's eye that I'd love to see. Even though I use mostly canned stuff (and I am trying to learn how to model), I consider my scenes to be my own creations. You could give 10 people the same set of items and end up with 10 very different pictures. Arrangement and composition are also artistic elements. To look at it another way: is a director less of an artist because he's on the other end of the camera? (Before you say, "Yes," imagine a film done by Steven Spielberg, as compared to Stanley Kubric or Ed Wood.) Cheers!
