Skilled at painting, say (8)
I believe the answer is:
artistic
'skilled at painting say' is the definition.
(I've seen this in another clue)
This is the entire clue.
(Other definitions for artistic that I've seen before include "Having a creative imagination" , "I stir cat (anag.)" , "Aesthetic, creative" , "Showing creative skill" , "Expressive" .)
