6. Okay, now get a blender. I suggest using 'grainy water 30', because it blends the underlying colors as well - most other blenders will only blend the colors on the current layer, even with the 'pick up underlying color' checked. Now, keeping in your mind where your lightsource is, draw two parallel lines on each feather, parallely to its length. It should mark the upper and lower part of the feather - and they needn't be 50/50 either! The line between those two blending lines, will be where the middle line of the feather will go. Now do this process for ALL the feathers. (Not kidding.)
