There are two ways I use these pencils, first, lay down colour layers and smudge with a Qtip which is what I did here, or two, wet the lead and draw in a circular motion with the wet lead, very effective for dark areas. The leads tend to dissolve in the water so I constantly dry them out under the heat of an old fashioned light bulb.
I start to sketch in the deep grass of the rise he is standing on with the regular pencils with very very sharp tips as I am outlining each blade and clump of grass. I start to outline trees with darker and lighter areas. I simply cannot say enough about the flexibility of Q tips for drawing, smudging and erasing techniques. They are the cheapest, most flexible art supply around. I use them all day, every day.
