All the suggestions above are great and so I am reluctant to feed one more into the fire but what the heck, I will throw one additional video reference out there for consideration. James Wappel is coming out with a bunch of 90 min+ videos (53 I think) that cover, in detail, basic through advanced painting techniques, color theory, and there are also a bunch of basing and terrain videos as well. I think the retail will be out in May/June timeframe but don't quote me on that. He is finishing up the delivery from the Kickstarter project at this time. I believe the videos will also be available in download format from cool mini. If you want to see a decent example of them go to youtube and search "James Wappel & Painting Pyramid" sand quotes and you will see listed some of the Alpha versions of a couple of the videos he created as updates to the KS project.
