Make the "Creative Design" come out of your camera. Experiment with different lenses and lagging sutters. You can always shoot "normal" stuff if you want to.
But, and I stress BUT. You must learn the art of photography. How light works...how to work lights. How apature and shutter speed effect the shot. Once you master that...the rest is easy.
Really think about what you are shooting and what you are trying to accomplish.
Examples of not so expensive sets but just great photography...
