This map is rather bland, although has allot of parental. And I understand it isn't currently finished, but if you wish to extend this parkour, it is going to have to improove. Try making it look more like a haunted mansion, and use more 'spooky blocks' (redstone tourches, pumpkins, jack'o'lanterns, slime blocks, ect) To try and get a bit more of a spooky sort of theme.
Good luck
