Stay sharp! Good quality pencils will allow the lead to be sharpened regularly. Needle sharp tips on your pencils are perfect for applying detail and getting the precision required to color intricate areas of a design. Thinner points will give you more control over the color produced, big fat rounded ends on your pencils make it difficult to get the brightest colors.
Get even! Producing a nice even color with your coloring pencil is all down to pressure. Push harder on your page for darker coloring, applying little pressure will producer a much lighter color. It is tempting to put lots of pressure on the pencil to produce the darkest color _ don't do it! Too much pressure will likely cause you to break your pencil leads, produce a scratchy finish to your coloring and give you less control. Instead, try applying your pencil with a little less pressure and use small circular motions with the pencil to get an even finish.
