I don't know what program you use, but you should fix the place in the green circle.
And what about the hood? How does it look, when the front end is black?
If you add a little angle to the white stripe on the side, the fxo would look more dynamic.
A black outline for the white stripe also would be cool. And some little decals, for example some white decals on the hood would look nice. So it looks a bit naked.
If I were you, I would multiply the default skin in an extra layer with the skin.
It adds some shadows etc...
But its your skin...
