That would be a good look.
Man it would be a lot of work, but if someone could vfx some trees (doesn’t have to be a lot) near the castle, it could show “nature taking over” from it being unused for so long and help it blend in. Same goes with the “valley” at teh end of the shot to add more of a forest … which may not be as hard since it’s not a close up and lasts not too long? (Me saying that who has never done this before 😛)
