my eye says the subject is the girl sharply in focus, on the right. She's 'leaving' the frame, taking my eye with her. But then, it's interesting how you have it, the clear to the right and smokey to the left with the girl dividing it.
Its a bit of an unusual placement of the main subject, back turned to a large and bright area. I agree, the leaving theme is implied, which is fine. Sounds like your surroundings limited you. I wish the door was either bigger or absent. I might try to darken the man in the bright sweater, but see if there is a way to selectively preserve the rising smoke and mist.
In a situation like with a strong focal point (woman) needing context to explain her actions what I try to do is "unify" the elements competing for attention by finding a POV of the camera that puts the context behind or in front so both are seen together, preventing the ping-pong dynamic that occurs when the eye must jump linearly to see the story elements.
I'm not suggesting you edit this image as seen below, the edit is to show visually what I'm suggesting above...
The POV and composition give the woman more balancing space in the direction she is facing, and the context of the urn with joss sticks is seen at the same time without the eye leaving the woman's hands, unifying them compositionally.
Better compo. The problem with the original is the subject and the fellow in the background are both facing right...right into an open door on the right frame border. More importantly, with the subject facing right, she leads the eye of the viewer out of the frame.
