Styles to me is just like window skins and themes that you would like to dress your desktop up with. You will change them from time to time to keep your desktop look interesting to you. However no matter which skin u apply to your OS, the functionality of the OS doesn't change at all. Therefore, when I approach my art, I am just merely interpreting what I already known, in different styles, but the fundamentals such as shapes and forms, light and shadow, colour contrast and harmony, perspective and composition are still there, just that I chose to override some of them at times to create new styles.
So far no one seems to accuse me for having too many styles, and I am happy cos drawing the same style over and over again can really bore me to death.
