He has. Good advertising, excellent teaching, and tack sharp, clear videography does not make him the best bonsai artist in the world though, is what I was saying.
I am not saying I know he is not, because I do not know. I have not worked with him, seen only snippets of his videos. I have seen some trees which are really good. But whether Kimura or kobayashi are not better? Or whether there are a few people hidden in places that have the same skillset? Dunno.
In any case. I think you should never state things in absolutes. He certainly is one of the best artists and one of the most well-known artists out there.
