Hi Yoshiharu,
If you say it was your training period, in what level you want to achieve?
Your works have described your talent. You have mastered the technique guy. I can see an oriental atmosphere covers the traditional one.
If you don't mind, I want to ask your steps to do your work. This is a private request, because I love your technique.
I would be very appreciated if you could answer my request.
