I am trying to render flames on my latest drawing. I am having a difficult time and need some advice. I am using Prismacolor markers primarily in the rendering along with Pastels and Colored Pencils all of the same brand. The car is '50's style sled, black in color. I can get the flames down all right, but I don't know how to go about fading them with the colors Yellow, Orange, and Red. Also, any advice doing the reflections in the Gloss Black part of the car?
