I am modelling a Shellby gt 500 which is quite similar to this mustang.... i think u need to look at some reference for the fog lights under the headlights... They hav a thick rim around the inset for the fog lights maybe u could try adding it

Rest of the model is looking quite spot on from what i can tell... maybe try to get rid of some hard edges that you are getting under the grills? on the bumper.... but looking good bro

As for the textures, the cars body seems a bit too reflective and looks more crome like, unless thats what you are going for i would suggest toning it down a bit.... I really like the mags on the wheels, they looking great!! I hope this critique helped and that m not too late
