Don't worry about trying to develop a style. Style is what you can't help doing. If you write enough, you draw enough, you'll have a style, whether you want it or not. Don't worry about whether you're "commercial". Tell your own stories, draw your own pictures. Let other people follow you.
Contemporary movies just drive me crazy. The violence and the sentimentality and the spiritual materialism and Theism and the incredible indulgence in ignorance is so claustrophobic.
