I forgot about these improvements a while ago, and I just realized them.

You can remove the borders by unchecking the "Draw Borders" box on any and every object (unless it's a detail, like a gas cap or a door border). The gaps between the wheels should be filled with a black polygon matching the shape of the car. Don't change the material of the glass panels with the material to get the desired color, simply use the HSVA sliders and the color picker above the sliders to make the panels blue. This should be set for the entire scene, including the car.

Again, don't use the brush tool. Instead, select the polygon tool, and hold the left mouse button to make perfect lines. This should apply to every detail.

The rims are too undetailed and uncentered. Make the rims from a reference image, and center them by using the grid tool.

The terrain looks too rough and when I try to drive through it, it occasionally stops the car due to how inconsistent it is. Use the same polygon tip above and try to make gradual yet rough terrain, or use the polygon tool and make terrain.

Don't use fixjoints just to glue objects into the background/another object. Instead, use the "glue to" tools in the geometry actions section.

Please read the entire message sentence by sentence. I split up the text into sections for easier reading, and you seem to ignore it, probably because it's too long.

sorry but i think this is the best i can do so far
