I have added Masahiko Kimura to the Bonsai Master Artist page. Mr. Kimura granted an interview to Bonsai Empire and it is really great to watch.

Interview with Bonsai master Masahiko Kimura Video by Bonsai Empire  At the 12:25 point of the video, Mr. Kimura gives some really great insight as to what qualities make a great Bonsai Professional artist. He lists 5 qualities that a professional should have. I found it interesting that he said some of his students did not possess some of these qualities.
