More than usual from art returned (5)
I believe the answer is:
extra
'more than usual' is the definition.
(I've seen this before)
'from art returned' is the wordplay.
'from' becomes 'ex'.
'returned' says the letters should be written in reverse.
'art' back-to-front is 'tra'.
'ex'+'tra'='EXTRA'
(Other definitions for extra that I've seen before include "Score not made by 34 [CRICKETER]" , "23 player?" , "appearing in crowd scene" , "Additional expense" , "additional supplies" .)
