Broski looks like he hopped out the car hoping he was at LA.
Lighting could be a bit better and so could the pose.
This is an example of what it could look like, good lighting/shadows.
A nice pose on the car and a nice scenery in the back to show the car is somewhere on the road.
It would be nice if the car was also actually standing on the ground, right now it’s just floating in the image, like the example @oreo gave, try making it so that the car is actually on the road, apart from that maybe some shadows & lighting tweaks and it will be great!
