Copied some landscape drawings (4)
I believe the answer is:
aped
'copied' is the definition.
('ape' can be a synonym of 'copy')
'some landscape drawings' is the wordplay.
'some' says the answer is hidden in the clue (some parts of the word are used).
'APED' is hidden within 'landscape drawings'.
(Other definitions for aped that I've seen before include "was imitative" , "Imitated like monkey" , "Imitated in every aspect" , "Imitated, mimicked" , "Caricatured" .)
