I cannot see where they brake any rules of nature or art. The so called bonsai rules are guidelines. They are for beginners and artistically handicapepd folks. If you follow them you create something that is not totally bad usually. But it isn not good either.
I posted these trees to play "devil's advocate"
Just because a tree breaks established bonsai rules doesn't make it a bad tree. However, it is my belief that if you break a rule, you should at least understand you are breaking it
For example, if you are writing a book and misspell a word, it is not necessarily wrong if you INTEND to misspell the word. However if you misspell the word because you don't know any better, that is not intent, but a mistake.
Take for example the first tree in the series. Normally if you were creating a twin trunk design you would want the trunks to split at the nebari. Having them split mid-way up the tree creates a balance issue, as well the potential "sling shot" design challenge. This is a mistake made by many beginners. However in the case of this tree, the asymmetry creates tension while the hanging branch on the left balances the design. End result - an award-winning tree not by mistake, but by design.
I wonder if I am making sense
