Disaster as artist in new trick messed up (5,5)
I believe the answer is:
train wreck
'disaster' is the definition.
(I've seen this before)
'artist in new trick messed up' is the wordplay.
'artist' becomes 'RA' (Royal Academician, member of Royal Academy of Arts).
'in' indicates putting letters inside.
'messed up' indicates an anagram.
'new'+'trick'='newtrick'
'newtrick' is an anagram of 'tinwreck'.
'ra' going into 'tinwreck' is 'TRAIN WRECK'.
'as' is the link.
(Other definitions for train wreck that I've seen before include "likely result of hard Brexit" , "disaster" .)
