Picture: "The Headland Beyond the Waters" (8)
I believe the answer is:
seascape
'picture' is the definition.
(I know that seascape is a type of picture)
'headland beyond the waters' is the wordplay.
'headland' becomes 'cape' (I've seen this in another clue).
'beyond' means one lot of letters go next to another.
'the waters' becomes 'seas' (sea is a kind of water).
'cape' put after 'seas' is 'SEASCAPE'.
'the' is the link.
(Other definitions for seascape that I've seen before include "Painting, maybe a Turner" , "work of art" , "Maritime picture" , "Painting of the briny" , "Painting genre" .)
