Artist son curses about having left pint (10)

I believe the answer is:

sculptress

I'm a little stuck... Click here to teach me more about this clue!

'artist' is the definition.
(I know that sculptress is a type of artist)

'son curses about having left pint' is the wordplay.
'son' becomes 's' (genealogical abbreviation for son).
'about' indicates an anagram.
'having' is an insertion indicator.
'left pint' becomes 'lpt' (I am not sure about this - if you are sure you should believe this answer much more).
'curses' with letters rearranged gives 'curess'.
'curess' enclosing 'lpt' is 'culptress'.
's'+'culptress'='SCULPTRESS'

Can you help me to learn more?

(Another definition for sculptress that I've seen is " Woman who carves".)

I've seen this clue in The Daily Express.
