Hi Joe, what most inexperienced bonsai people don't know is that a "bad" bonsai design often does not have to be redesigned, especially if it's a new planting. Take good care of it for 30 years, let it grow out, clip back, fill in some negative spaces with branches, develop some age and patina, and it will be beautiful. That's what this Chinese gentleman did. Now if you don't have 30 years, or if you must have an instant bonsai, then by all means, rip it out and do it over again. There's nothing wrong with that either. The trick is to know when your design is good enough and don't have any fatal flaws that would get worse over time. But to a typical Chinese bonsai artist, there is even no such thing as a fatal flaw to a tree, because they like all the weird lines, the weirder the better. Some time it works some time it doesn't. It's a lot harder that it looks.
