@Djtommy - Thank you very, very much for posting these photos. I think you posted over 100 images. That is a lot of work. Thank you. I always learn something from studying the photos of Kofuku-ten and Taikan-ten every year. Beautiful, thank you.
@Woocash - You know I've been seeing and hearing the occasional complaints about the "green helmets" of Japan for many years. You are not the only one. I'm going to bust your chops a bit, but don't take it personal, my target is the many that repeat your complaint. I'm not picking on you specifically.
Almost without exception, the ones who complain about the "green helmets" of Japanese bonsai, simply do not have the skill, or at least have never demonstrated the skill necessary to possibly create that level of bonsai themselves. The skill that goes into those "green helmets" at major shows like Kofuku-ten is incredible. If you are serious take a close look at those trees, you will see incredible skill in detailing. Way beyond the skill level most USA and UK based artists display. The handful of artists in USA and UK that do have the skill to create those "green helmets", never complain about them. Reason is respect. Those "green helmets" take incredible work. And even if you are not fond of the silhouette, when you look at the fine detail, you can't help but be in awe of the skill that went into the tree. When you can, take a serious, detailed close look at a Kofuku-ten or Taikan-ten level "green helmet" and seriously contemplate the detail work that went into creating that silhouette. And in doing so, you will notice, they often are not as rounded or uniform as they looked at first glance. They have a lot of detail in them.
I know I don't have the skill to pull off a "green helmet" nor a "formal upright", but I appreciate the skill those styles take, and will never "dog 'em" just because the outline isn't my favorite.
