When come to a style that is going to distinct you from the rest of the world, there will never be a written instruction on how to define and where to find your own niche. The possibilities is endless. It can be the technique you're using, the unique point of view you look into a ordinary subject, or perhaps something that comes from your heart. As for me, 'personal style' comes when you have imprint 'yourself' into your piece of artwork, especially your thoughts, your emotions and the way you see the world. People will feel your existence within the artwork itself.
