Adventures in palette knife painting

I gave palette knife painting a try, I think I overdid it in a couple areas but it was really fun and I mostly like how it turned out. The tree was from a reference photo I found online but I could tell it was a grand old thing, and was sad to see parts of it were dying.

 Here's the under painting, prior to attacking with the palette knife. I like the simplicity of it.
