Jason Seiler is an illustrator who lives in Toronto. He specialises in creating caricatures, portraits, and comedic illustration.
He also teaches in caricatures. He started out in an unusual way for an illustrator to be noticed, getting into trouble drawing his history teacher, as a caricature in high school. He first became noticed by his principal at the time, who hired him to draw caricatures of various faculty members. He went on to study fine art illustration at the American Academy of art in Chicago, after this.

He has published two books on his artwork, featuring many humorous images from his illustrations. he has also published an instructional DVD, called sketching with Jason Seiler.

Some of his many clients, include TIME magazine, The New York Times, The Wall Street Journal and MAD Magazine, New Line Cinema. He uses a lot of digital manipulation in his varied artwork, especially with his caricature work. (See images)

He is a member of the society of illustrators in New York City. He also has been an art instructor for a few years.

Interestingly, his digital artwork resembles that of caricature art. I have enjoyed researching this artist, but I do not wish to take influence from him, as I don't want to go down the route of this style. I will say though, that he is an incredibly talented artist, nonetheless.
