This is not how you paint a car, with cheap products and any lack of direction in the art part.

Professional grade car paint is really expensive stuff, for several good reasons: It does not change color or fade overnight and often has metallic dust or some kind of pearly "glitter" embebbed.

A professional car painter will add also a hard layer of lacquer to protect the painting, uniformize the design, and add reflections and gloss (sorely lacking there). The car will not reflect light in the same way as a propperly painted work and will gets scratched and worn in no time.

The design here is multicolor but totally flat and random (there is science in arranging adjacent colors also). Artistically is a mess. There are not sharp borders defining areas and gradients are badly executed. Not a common theme or a good idea to express, just plain chaos (in a not good way).

Of course she can made anything with her car but lets not pretend that is a great job, not even mediocre. There are two good examples of how you made a unique car:
