Yeah I agree, I wouldnt worry too much about it not being written off. It looks like its mostly panel work and nothing too serious. Many panel beaters do pretty good work, make sure you sus them out and have a say in who will do the repair if you can. Hopefully when you get it back it will be better than new. The key to the whole thing is for them to do it right the first time. All too often when you have to take it back to get something fixed, they usually break or damage something else.

Dont forget to get the insurance company to do the paint protection as well if you had any.
