i still working on this project

,this car make me feel so good,i love how aggresive i make it

the car is still pretty toon, add more reflections in the side always taking a cue from the donor.

as said more refs needed you got all the right basic shading but you need to add more depth to them, keep using your reference the lotus for colour guidance, the lightsource is top left of car so front of car needs to be darker
