There's inconsistency in implications:
there is implication maid_marian -> robin_hood_(disney)
there is no implication robin_hood -> robin_hood_(disney)
I was about to suggest the latter but then I thought that not all pictures with robin_hood are about the disney one.
Then I was about to suggest unimplicating maid_marian but it doesn't sound good either.
So, how about aliasing robin_hood_(disney) -> robin_hood_(copyright) and implicating both character tags (and probably some more) to it? I don't think that there is much sense in making separate tag for not Disney robin hood.
