An extremely large floating island ...

An extremely large floating island (just the island should be 70 blocks tall and 400 blocks wide minimum) inspired by fantasy elven forestry/greenery. The island should have one main focal point on the bottom with other small similar spires off on the sides. Put a large house in the middle that's sitting on a hill that incorporates fantasy elven architecture with steampunk. The color palettes for the house should incorporate mauve, muted green, and pastel yellow. Scatter other aesthetic choices around the island that incorporate this blend of fantasy/steampunk. Finally, make visible pathways from the house that will lead to future farms that I will personally build, so leave areas where I can build those farms.
