I agree with the other posters, that is indeed a stunning piece of busy wood.
You have also done a great job with it, the finish enhances the wood well and in cases like these, that is most important.
Nature has strange way to do things, I can say that I have lost and will continue to lose lots of good logs due to the wood borer creatures and other sorts of infestations that wood tends to get, and while I can not explain why trees have to die as a result, I can also say that, some of the best pieces of wood I ever seen/put my hands on, area woods where those creatures enter the wood with ist's fungi and created some of the most spectacular works ever seen, that I know...!
