I just watched this video on the Wholphin website. I don't mind saying it's kind of boring. But it's just an excerpt, so maybe I need to see the work in it's entirety to really appreciate it. I do like his method.
Perhaps the next film in the series is more engaging, How to Draw an Apatosaurus.
Also if you've looked at the links above you should go ahead and look at Jason's art available at 20x200. I'd like you to buy one of the Edition of 2.
And in conclusion, I'm thinking about buying One Hour of Art from Mr. Polan.
