Nice start so far. Out of curiosity, are the chests and torches going to stay? They're a bit of an eyesore but everything else is very nice.
I think if you made either pedastals for the torches, or infinite flames using nether rack it would add to the aesthetic.
No I plan on making chest rooms, and those torches have been removed since i've got the mushroom biome
updated version: credit to MuffyCakes for helping me out so much and I fixed the "they'res" for your concerns.
