Favorite artists

My favorite artists are Salvador Dali, Georgia O'Keefe, Picasso, and of course Michelangelo for the Sistene Chapel (which sadly you are not allowed to take pictures in there, or else I'd post one).  Besides being the greats and classic and creating new ways of using color and shape, their works are just beautiful.  For more modern day artists, I like Christian Lassen; we have two of his paintings in my house.  They're gorgeous beach scenes from Hawaii mainly, and the colors are bright and rich. Who are some of your favorite artists?
