Astute misrepresentation of figure (6)
I believe the answer is:
statue
'figure' is the definition.
(statue is a kind of figure)
'astute misrepresentation' is the wordplay.
'misrepresentation' is an anagram indicator.
'astute' is an anagram of 'STATUE'.
'of' acts as a link.
(Other definitions for statue that I've seen before include "Monument" , "As created by 3dn" , "Three-dimensional work of art" , "Sculptured likeness" , "artwork" .)
