I never find any painting easy to do, they all present challenges even when I try to keep it simple. I'm painting a lot of rock and streams at the moment, what has got me going, is the use of the palette knife. It's so different to my normal detail with a brush, and I'm enjoying it. The next painting I do of a bird is going to have a palette knife background, who knows, it might be the way to go. Time will tell.
