I got totally on fire with this one. I love to see ghost flames on cars, but never really paid any attention how they are actually done, and I was too lazy to Google it.
This is my artistic interpretation using Nail art pens in red, orange and yellow for drawing flames over white background. Yellow is Julep - Daisy, and orange is Julep - Kaylen. I did dry brush over yellow to simulate more flames.
I actually liked how this came together, regardless of my freehand fail.
