Love character's style of painting (2,3)
I believe the answer is:
op art
'style of painting' is the definition.
(I've seen this before)
'love character's' is the wordplay.
'love' becomes 'o' (love means zero in tennis).
'character' becomes 'part' (a part in a play).
'o'+'part'='OP-ART'
(Other definitions for op art that I've seen before include "Modern style" , "It may give the impression of movement" , "abstract school" , "sort of painting" , "Illusory paintings" .)
