Doesn't l ooks like any significant damage, to the main structure of the car.
Rear bumper, impact beam under bumper, gonna have to cut and put in a new 1/4 panel, new trunk, seems like the basic items. Nothing too major to be concerned about.
Make sure to bring it to a good shop, and or certified bmw body shop, and make sure parts used are OEM! check insurance estimates to see if there using oem bmw parts, and make sure to tell ur shop u only want oem parts.
