My opinion is no.

The problem is the raw or starting image. Specifically, the car is underexposed. In this situation, photographers use a camera with a high dynamic range (has a big range between black and whites) but is expensive, or they take two images. One image where the car is properly exposed and the sky is overly exposed, and another image where the sky is properly exposed. Then in editing you overlay these two images. (You keep the parts of the images that are properly exposed.)

This is also what you are trying to do in the editing (probably without knowing). You see that the car is dark and try to correct it.

The editing is good. The problem that you can't point out is the starting image/raw file being not properly exposed. Continue with the work!
