Welcome!
Before I say anything, this is meant to intentionally be a low-poly artwork, like an old game, right?
If it is, you could add a sky background, I wouldn’t expect a pure black sky with this art style. I could see either a low-res HDRI background working well, or a simple gradient.
What stands out to me is the “not-quite fish-eye (“wide-angle lens”) camera distortion.” I think you’re trying to pack too much content into a single frame. (And, a “portrait” orientation to that frame, probably to include the skyscrapers.) The camera is also in the “geographic center,” when the interesting bit might be the car which is now emerging from that garage.
So, maybe, take the unchanged model that you have, and experiment with the camera. If this were a real-world setting, exactly as-is, and you were tasked to film it in real life with ordinary camera hardware (including as many “booms” as you like), where might you place yourself? With my suggestion, change only the placement and settings (lens, focus and orientation …) of the camera.
