Agreed. The best inspiration comes from where you live.
I keep thinking about a bald cypress bonsai in Houston. The base of the tree was bizarre and unappealing to me. Then I spoke with the artist who showed me photos of trees growing in the same way in the Houston area. Suddenly, I loved his tree.
We need to do more to represent the natural styles in our own area than imitating the styles of Japanese bonsai. After all, they're representing the natural styles in Japan.
