My comments are on the drawing only.

Your line quality need a lot of work, the lines should be free and loose. Draw from your shoulder not your wrist.

The wheelbase should be 3 wheels at least for any car, use this rule a minimum.

You need more tumblehome in the greenhouse of most all the cars.

I would suggest on a lot of practice in side views. Draw your wheels first, make them 3 wheels widths apart. Then start laying down loose, lines drawing with you shoulder and drawing through with nice continuous lines.
