Yes, all my art, fashion designs, logos and even web designs start out as vectors, but once finished they cease to be just vectors, and turn into what I intend them to be.
I used to think like everyone else, and focused on grunge signatures, but it took about 2 before I realized I didn't want to be like everyone else. After that I experimented with doing odd shapes, started vectoring in Photoshop®, which evolved into my own style. Maybe later I will also post up the signatures that lead to my large art.
