8. Now get a few nice colors laid out, and draw a big bunch of tiny little lines going at an angle against the middle line on each feather. Make sure the lines on both sides of the middle line are perpendicular among themselves. Use lighter lines where the light hits your feathers, and darker lines where there's shadow. Mix colors, too, so that your feathers look shiny. Do this till you have detailed out all the feathers in the layer. Save.
