Personaly I think writing is a good tool. I think it is a better tool when accompanied by what you did on a tree to make it artistic. Writing for writings sake is sort of OK but what do you really have in the end. Just a bunch of words.
Write an ebook based on how you took raw stock to an unbelievable tree in whatever years it took, based on your sound principles. Then you will have something to be proud of. Show me how your principles work and how they relate to bonsai in the big picture. That is the element that is always missing. Showing exactly based on experience from an art background, in useing all these art rules in context with a tree.
Drawings just don't so it for me. I come from a construction background and can tell you first hand that an architect can draw it but it can't always be built. I can't tell you how many times I have to call the architect and find out just what it was in his mind that made him think it could be built that way.
Andy has done a fine job of telling us what to do. Hopefully you can show us what to do. Don't reinvent the wheel, it's already been written one way. Do it so much better that everyone will forget that Andy wrote something so rudimentary
