I see a lot of tutorials and resources for drawing in general, but specifically I want to know how to color well using colored pencils. It's for a first-time art commission/prize.
I don't want to just fill in shapes with a solid color. I want to know how to draw smooth surfaces, lighter and darker areas, color on top of color, etc. I want to know when I should use color pencils, fluorescent pencils, metallic, watercolor and pastel pencils, and when or if I should use chalk or crayon blocks.
