That's suck. I would take it back to body shop to fix if it was me. I have some problem like F1 hood and rear gt/p bumper that body shop did little mess up. I return it back and tell them about that problem. They fixed it and now it is much better. Kind waste money if you decide not go back to same body shop to find other body shop to more pour money on it. That's my opinion for save money, less headache and be patient.
I did draw my F1 hood like your as black color last weekeend. Kind okay to me but I believe SD with black line is much better than F1 hood. Maybe get black GPO grille to finish the good look? I plan to get mine later.
