Alright I don't look at Van Gogh's or Picasso's, or I guess I could say I do but I really cannot say I critique because in a sense they are above or beyond me, and generally just not something I really like. I love Mark Ryden and I think he is awesome, here is one of my favorite pictures by him.
It always hard to say which artist is my favorite but right know it would have to be Egon Schiele, Gustav Klimt, Olly Moss, Brandon Bird, and Brad Holland
*sigh* This is a hard one... I almost hate making a list because I feel bad if I forget someone. The latter four on here are mainly here because they've been an influence on a lot of my own art.
Alphonse Mucha Henri de Toulouse-Lautrec William Adolphe Bouguereau Caravaggio Norman Rockwell Jamie Hewlett Charlie Bowater Tracy Butler (I normally don't care for anthro stuff, but her comic, Lackadaisy, is just...damn.)
My favorite is most likely David Choe (before he painted Facebook) but he was still a good artist after painting facebooks's office. Here is a sample of his stuff.
I really enjoy the works of both Dali and Van Gogh along with many others.
Currently I am obessed with the works of Audrey Kawasaki www.audrey-kawasaki.com/ I have been inspired by her works in my own field of apparel design. In fact, I am currently creating a dress inspired by one of my favorite paintings by her for a Elsa Schiaparelli inspired student exhibition. For those of you who do not know who Elsa Schiaparelli was, she was a fashion designer during from the late 20s till the 50s. Her designs were greatly inspired by surrealism. She and Dali even collaborated on a few of her garments. en.wikipedia.org/wiki/Elsa_Schiaparelli
I know many people put older artists on here (Gogh, Picasso, Dali...) and I love those guys (and many other "older" artists) but my favorite artist has to be Bill Watterson, creator of Calvin & Hobbes.
Discovered his stuff when I was a little kid in elementary school and I've re-read everything he's done through out my life. It was one of those books that I could read and it would make me laugh and just feel good, even when there was stuff going on. When I finally had enough money, one of the first things I ever bought was his entire collection of work.
I know it's more "newspaper comic" style but I consider Bill to be among the greatest of artists there have ever been.
