Steve,
we were all beginners once, some of us for longer than others. Please don't ever be worried about posting something, especially when you've made such a great job of it.
It's got a very good shape and it's well finished also you've kept the bark on which is not always easy.
Something that would only be noticed from experience is another cut or two deeper would have thinned the natural edge just a tiny bit more and kept it a constant thickness around the form. Having said that, it's so nearly there only a few would notice so don't worry about it.
A great piece, well done.
