I see it more like composing then posing, I fill a scene with things you bought, downloaded or made myself. There is still a lot of creativity involved in that process, more comparable to a studio-photographer, who sets up his lights and arrange his own scene.
A music composer doesn't perform his opera, he still will need singers and players, Mike Oldfield is perhaps the only exception.
