Draw girl's head captured by artist (6)
I believe the answer is:
magnet
'draw' is the definition.
(both can mean something attractive)
'girl's head captured by artist' is the wordplay.
'head' indicates taking the first letters.
'captured by' means one lot of letters goes inside another.
'artist' becomes 'manet' (I've seen this before).
The first letter of 'girl' is 'g'.
'g' put inside 'manet' is 'MAGNET'.
(Other definitions for magnet that I've seen before include "It has the power to attract iron" , "it could be a draw?" , "Source of attraction" , "Piece of metal that attracts iron" , "One that attracts" .)
