From what I'm seeing, its nice to see you're already improving enough!

My only suggestions is to modify the break limit on the axles depending on the strength of a part or reduce the amount of axles; the car is too slow and strong to even suffer a scratch! I'd recommend to add variety with the color sliders; I could barely see the car's shape with the sky's color close in similarity in relation to the body color. I'd also recommend decreasing the border size by a bit too.

If you want to be more daring with your crashable vehicle scenes, try adding interiors, driver ragdolls, airbags, etc. Good luck with your scenemaking!
