Hi Lukas,
this damage doesn't look bad and I can't imagine that this is a constructive total-loss of the car. Isn't it possible to involve an accident assessor? Here in Germany you've got the right to assign one, naturally at the expense of the insurance.
Imho the main chassis beam can't get really damaged in this case, therefore it's no total-loss. I think the damaged components are: the outer and inner bumper (of course ), the lock carrier, the headlamp (note: there's a repair kit available for the upper mounts), the lock carrier and maybe the fender.
When the mounts of the outer bumper don't fit anymore, loosen the screws all around the fender and try to fit the attachments.
btw: Even if there's anyone here with construction documentation, we're not allowed to publish any copyrighted material. sry.
