Mark, I appreciate you have set yourself standards in form, and maybe this piece does not meet some of those pre-determined criteria, for myself being an individual that looks at a piece of worked wood for its ability to show off natures beauty, it is fine as it stands. I've never perceived a tree as imperfect (what does an imperfect one look like?) although I've never seen two the same and am never bothered by an asymmetrical turned form.
I'd be happy to give it shelf room and like the informal edging you have achieved, mimicking a bark edge with a finish better than a less than perfect natural one.
