Like most people, I have a bunch of links in my bookmarks that I check every morning while I scoff my oats and banana. Right now I'm loving the Gurney Journey, it's one of the ones I read last as I like to to be mulling over whatever he's talked about in that entry as i begin to start work. He's a very industrious disciplined guy, and my vague hope is that some of it will rub off on me, as I'm the complete opposite.
My wishful thinking aside it's a great resource or pick me up for any artist.
Oh, I should add that among other things James Gurney is responsible for the modern classic Dinotopia
