Meet painter, remarkably self-indulgent (11)
I believe the answer is:
intemperate
'self-indulgent' is the definition.
(similar in meaning)
'meet painter remarkably' is the wordplay.
'remarkably' indicates anagramming the letters.
'meet'+'painter'='meetpainter'
'meetpainter' anagrammed gives 'INTEMPERATE'.
(Other definitions for intemperate that I've seen before include "Drinking alcohol to excess" , "wild" , "consuming alcohol to excess" , "Lacking self-control" , "indulging to excess" .)
