Work of art superior in taste, maybe (6)
I believe the answer is:
Here is my best explanation:
'work of art' is the definition.
'superior in taste maybe' is the subsidiary indication.
'superior' becomes 'u' (I've seen this in other clues).
'in' means one lot of letters goes inside another.
'maybe' indicates an anagram.
'taste' anagrammed gives 'state'.
'u' put inside 'state' is 'statue'.
(Other definitions for statue that I've seen before include "artwork", "Sculptured figure", "Sculptured person", "A carved image or effigy", "Carved effigy", "Figure, effigy", "Eg, the Venus de Milo", "Three-D human representation", "Monument" and "Still work".)
