Kuzuhara Sensei's critique of a display at the Toko Kazari competition held at the Clark Center for Japanese Art and Culture...The picture on the left is the original display, and the photo on the right is Kuzuhara Sensei's photoshop suggestions to improve the display.
First off, the flow of the main tree and the placement of the display are opposite. In the case of using this main tree, it should be seated on the right hand side of the display, to make it a right to have it become a left flowing display. (Sashoute or Migishoute, I am not sure on the correct reading if it is considered one word or mixes on and kun yomi), because the bonsai's left hand side will create space. A tree that flows to the left should have the pot placed a little more to the right.
But because it was set up to be a display on the left flowing to the right please understand what I will say from this point on. This tree is not yet a finished bonsai, and I have done a virt to show how if it were to be a finished bonsai that was a Hidari Shoute (Flowing to the right) display how I would try to style it.
In the revised picture the pot, and foliage, as well as the table and accent placement provides more balance for the display. Additionally, the picture of the waterfall in the scroll follows the same pattern as the tree and is redundant to the display, and I slightly amended the picture in the scroll to try and minimize this effect.
