Yeah, looks fine. If it were me tho i would expect a brand new and painted mudguard for my scoot payed for by the person who backed into you, or their insurance. You did nothing wrong so why should you lose out and have a damaged scoot?
I got rear ended at a junction last year and i only had minimal damage to the scoot but i made sure any damaged parts got replaced ny the other drivers insurance. Had no probs at all, they paid out in 4-6weeks for new scoot parts.
