I'm going to post here some links to other artist's galleries I like or to some blogs that interest me. (I think I'm not going to put here URL:s to artists that I like but for sure everybody knows, like Dave McKean or Mark Ryden.)

First the webpage of the superior L.A.illustrator James Jean:
http://www.jamesjean.com/
This one also includes a blog about works in progress, I recommend!

Then a very interesting scifi/fantasy illustration oriented blog:
http://www.stainlesssteeldroppings.com/index.php?cat=11

You can also spot from Stainlesssteeldroppings couple of fantastic artists, for example:

(portfolio of Chris Appelhans)

Then the portfolio of Jason Chanart
http://www.jasonchanart.com/gallery.htm

Jason Chanart can also be found from the marvelous http://www.conceptart.org/
I think concept art is The Thing for me now. In my opinion some of the best design stuff is nowadays made by concept artists.

One of my favourites what comes to concept art:
http://www.princeofpersiagame.com/us/media/conceptart.php
(I think most of the concept art of "Prince of Persia"-games is done on top of 3D renderings. May be not the characters but the backgrounds and the scenery.)
