Artist's joke representation of nude royals (6,8)

I believe the answer is:

joshua reynolds

'artist's' is the definition.

'joke representation of nude royals' is the wordplay.
'joke' becomes 'josh'.
'representation of' is an anagram indicator (I've seen this in other clues).
'nude'+'royals'='nuderoyals'
'nuderoyals' is an anagram of 'uareynolds'.
'josh'+'uareynolds'='JOSHUA REYNOLDS'

(Another definition for joshua reynolds that I've seen is " portrait painter".)

I've seen this clue in The Independent.
