Recommendation:

One of the best blogs I have seen is one belonging to artist James Gurney which is entitled 'Gurney's Journey.' It is updated several times a week with helpful tips, techniques, and interesting insights into both art and history. Even if you are not an artist, you will likely find this an interesting read. Gurney is most widely known for his terrific illustrations in the Dinotopia series of books. His blog can be found here at http://gurneyjourney.blogspot.com/ . Enjoy.

Additionally Mr. Gurney has a very informative Youtube channel which can be found here https://www.youtube.com/watch?v=dCwscX1SAKE .
