OK im not sure what direction you're going or what end look you are looking for but I tried to use some of KLUE's pointers and re-rendered your car.
changed the spoiler to a Supra Style, slapped on some rims (sorry they were the only ones that were at the correct angle) opened up the front and removed your LED pin lights and made a shaded orange turn/park light where the fang use to be, removed the front carbon piece and meshed out the front and extended the light cavity then smoked it out. Re-shaped you a front lip too. (see i'm not all bad!)
