This series of eye illustrations is a personal project form the portfolio of the Spanish design studio Cranio. Cranio is an illustrator and graphic designer who's worked for several different agencies including Nike and 8by8 Magazine.
The project is called 'Look at me!' and its study into the details of the eye and how they reflect various emotions. By looking at the expression of one eye in the illustrations, you can imagine how the rest of the face might look. It's interesting to note that from one facial feature, we're able to grasp the full emotion.
The illustrations are all done in shades of black on a beige toned background. The simple illustrations clearly portray the intended emotions.
