Have a look at these great doodles by Lei “Leight” Melendres, a freelance artist from the Philippines. He does all kinds of art: vectors, photography, photo manipulation, typographies, etc.. But he is best known for his doodle art. His motto is: “If you can’t be original, at least do your best to be UNIQUE with your concepts.” And that’s the least you can say about his doodles.
