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.
Neil GaimanThe only thing that kept me going was stories. Stories are hope. They take you out of yourself for a bit, and when you get dropped back in, you're different- you're stronger, you've seen more, you've felt more. Stories are like spiritual currency.
Neil GaimanThere's never been a true war that wasn't fought between two sets of people who were certain they were in the right. The really dangerous people believe they are doing whatever they are doing solely and only because it is without question the right thing to do. And that is what makes them dangerous.
