Hi Ed....even with your blessing, I wouldn't wish to be negative - just constructive.
As a form, I think it's great. The profile shows a pleasing, flowing line right around it. The textures intrigues me and certainly does give the impression of copper windings.
So all seems well until I ask myself, 'Why wood'? I've had this concept stuck in my mind for years. I've always believed that the wood should be visible, even if only in part, but for some reason I can see, looking at this piece, that you had both a form and a texture in mind, so the answer to my question, 'Why wood'? is simple. Wood is what we work in. Wood is the medium that we can shape. We can't shape a piece of plastic, or clay, or metal into this form as the necessary skills are not transferable, so we start off with a piece of wood. What you've ended up with is a celebration of form and texture - the fact that it's made of wood is not relevant, not important. I think I just realised that sometimes I need to see the form instead of to look for the grain.
Cheers, Ed.....Les
