Astonishing work!
This is a real piece of art. Especially impressive are all those little planes. I'm not surprised that this Kamikawa Maru took you nine years. From my own scratch building experience I know that it's not a quick and easy process. Research, calculations and measurements take a lot of time too. Not to mention that we all have a thing called "life".
But at least, there's (almost)always satisfaction when we can see our models completed.
