I totally love the netherworld and would love to help out, I'm pretty good at building interiors and such too, so I think i could be useful. Also, I think, since it's said that Yuyuko's body is sealed inside the Saigyou Ayakashi, it might be cool to have like a tomb or something you could get to from the back of the tree and like have her human form's head inside or something. I also think the tree could do with longer branches that go to just one block in diameter and a few more blossoms.
