Oriental art work ultimately attracting deep breath perhaps when removed from case (4,2)
I believe the answer is:
kung fu
'oriental art' is the definition.
'kung fu' can be an answer for 'art' (I have seen 'Martial art' mean 'kung fu' so perhaps 'art' could also mean 'kung fu'). I am not certain of the 'oriental' bit.
I don't understand the rest of the clue.
Can you help me to learn more?
(Other definitions for kung fu that I've seen before include "Unarmed Chinese martial art" , "Chinese system of unarmed combat like karate" , "'A Chinese martial art (4,2)'" , "fighting" , "Chinese type of karate" .)
