It's very hard for me to narrow it down to just one. I'm influenced and inspired by so many. Picasso Andy Warhol Aubrey Beardsley Jackson Pollock Mark Rothko Kandinsky Miro...... and so many more so I'll stop now.
I know it's cliche, but Dali is a personal favourite. Also Francis Bacon, and Barbara Hepworth (do sculptors count?) I generally don't like a specific artist though, just one or two pieces by them.
Dali... I guess.... though I do like a lot of modern art, most of which I'm sure is by the same person... i just don't know who that person is.
william blake,max ernst,degas,rebrant,jake nad dinos champman,chris offili, burne jones.........lotsa pre raphelite artists
mmm...loads i like Escher, John Piper, Kiefer, Georg Baselitz( sinece today when i went to the tate modern) and Hume, Degas, Ernst, Bacon, Schiele, Modigliani ... Roly.xxx
