Shrewd statue design (6)
I believe the answer is:
astute
'shrewd' is the definition.
(I know that shrewd can be written as astute)
'statue design' is the wordplay.
'design' indicates an anagram.
'statue' with letters rearranged gives 'ASTUTE'.
(Other definitions for astute that I've seen before include "Clever and canny" , "Peerceptive" , "Shrewd, quick to spot advantage" , "Shrewd and clever" , "Statue (anag)" .)
