That's a really good attempt!
The brush actually looks really good in terms of where the reflections are and the overall lighting and tones
Where it needs some work is just sharpening up some of the reflection edges, and smoothing out some of the colour around the vents - it looks a bit uneven and brushy there
The other mods are good too - the rims and bg seem to fit well
The only major criticism is that the interior and front grille (left from the base) seem to be low quality and don't match the lighting of the rest of the image
Other than that very good try
