Good work! Always good to exercise new skills, on something other than a "good" model LOL
For some additional detail effect, look to the edges (sides) of the clear lenses, on the real car photo you can see a black gasket around the edges
You can simulate this effect well by sanding smooth, using a fine emery stick, to make flat edge, and then paint easily by hand with flat or semi-g black, the fine edge of the black will be visible from the front
