Fictional character from Charlotte, as newly portrayed by artist (8,5)
I believe the answer is:
scarlett ohara
'fictional character' is the definition.
(character from Gone With the Wind)
'charlotte as newly portrayed by artist' is the wordplay.
'newly' indicates anagramming the letters.
'portrayed by' is a charade indicator (letters next to each other).
'artist' becomes 'RA' (Royal Academician, member of Royal Academy of Arts).
'charlotte'+'as'='charlotteas'
'charlotteas' is an anagram of 'scarlettoha'.
'scarlettoha'+'ra'='SCARLETT OHARA'
'from' is the link.
(Another definition for scarlett ohara that I've seen is " GWTW heroine".)
