Painter Vinita Pappas has started a site called Create 38 where she posts video demonstrations that you can paint along with, and then post the results in the members' gallery. I read about Create 38 on Sharon's blog, the Flat Sound of Wooden Clogs; Sharon did a beautifully atmospheric version of this scene with gorgeous greens.
These are my paintings of her June reference photo of a vineyard in California. I did the 9x12 painting, below, first, yesterday. I painted quickly while watching Vinita's video and made a mess of the middle ground (those lumpy trees!). I painted the smaller version today, just trying to remember some of things Vinita said--and especially trying to hold my brush the way she does: out at the very tip! The middle- and distant trees are still not so pleasing to me, but it's an improvement.
