Ok, so I should be working, but I checked my google reader and just had to share this one with you. If you are not already following James Gurney's blog, you really should. http://gurneyjourney.blogspot.com is filled with practical advice and plenty of art tips, not to mentioned that it's very inspiring. I love the posts when he walks us through how he creates images.
His book "Imaginative Realism" is almost out so he's posted some promo clips for it. This last one just cracked me up. Enjoy.
