A frankenbuild - a mashup of a bunch of my previous classic builds modified special to fit together, and cleaned up inside afterword to lock it all together as one. Then flipped materials to create a new theme to settle in with our cherry blossom custom biome. I repurposed my two dragons and pasted them in with it, along with a few god trees I flipped to look like cherry trees to seal in the fantasy look.

Created with World Edit and Creative, taking about 9.5 hours. Build is approximately 400,000 blocks not including air.
