I like Vector style, it make real life people into cartoonish people in the sig which great. The only thing I dont really like is the font, it plain and simple, and it's not at a good place in my mind. But other then that I really like it my friend, you should keep doing some like that because it's really nice.
Oh MJ you make me laugh the render was cartoonish. Vector is when you use mostly the pen tool, thats all. Also I do not look for a person that i want to make a signature around I see a render I like and make a signature around it. Also you people have a major hang up on text. You do realize it is suposed to look simple rofl. I hate downloading a new style font everytime I make a new signature rofl.
