A lot. And not all of them comics artists. Off the top of my head I can include Americans David Mazzucchelli, Norman Rockwell, Bruce Springsteen, Franklin Booth, Frank Miller, Bernie Wrightson,  British artists Barry Windsor Smith, Frank Bellamy, The Beatles and Dave Gibbons, Asian artists like Jim Lee, Akira Kurosawa, Katsuhiro Otomo, Stephen Chow and Goseki Kojima, to the odd Kiwi like Peter Jackson, to a whole bunch of Filipino artists like Francisco V. Coching, Nestor Redondo, Alex Niño, Juan Luna, and Alfredo Alcala.  

If I see artwork that I like, consider me incluenced because a piece of art always has an effect on me, whether it's good or bad.
