Poor artist embracing new movement (7)
I believe the answer is:
transit
'movement' is the definition.
(I've seen this before)
'poor artist embracing new' is the wordplay.
'poor' indicates anagramming the letters.
'embracing' is an insertion indicator.
'new' becomes 'n'.
'artist' anagrammed gives 'trasit'.
'trasit' going around 'n' is 'TRANSIT'.
(Other definitions for transit that I've seen before include "In - - (en route)" , "Passage of a planet across the sun's disc" , "Journey across" , "In migration" , "The carrying of people etc" .)
