Luckily that damage looks limited to the wing. Possible lights damage too but nothing major. The decision to repair or replace the wing will depend on how much deformation has occurred in the metal. If repair then be wary about a lot of filler being used.
About 5 years ago a neighbour bumped into the rear wing on my car causing a small dent. A dent repairer did a great job of teasing it out. No paint damage luckily. £80 and about 30 minutes.
