I like whole idea of ghostly-themed biome (against corrupt and bloody ones), but I don't like the names. Maybe not Torment, but Necropolis or Cursed Land or Graveyard. Ghostwood is fine, but tombstone and and tombsand are meh, better soulstone and soulsand, "pale ice" instead of tomb-ice. Also Tormentor mob looks meh, not ghostly enough. And "strange flesh" - what strange in it? Maybe soul core or smth else.
