I like the smaller walnut form the best. When I look at it, my head says: this isn't following classical hollow form shape ideals at all, but the heart says: yeah, this has character.
I am not sure what to do with the ash form. I personally would have liked to see the shoulder to turn in more, but then it sounds like your hand was forced a little. The thing I am most unsure about is the colouring. From what I can see all you have done is make a piece of ash look like a piece of pine. But maybe I am missing the point altogether.
