! There are many talented colored pencil artists who offer tutorials. I did a search on google and found several. We also have a classroom for drawing and in that classroom you can find lessons on colored pencil drawing here:http://www.wetcanvas.com/forums/showthread.php?t=316172
It is very useful.
There are also some really good colored pencil artist books that are helpful. You will also find many good tutorials in the Colored Pencil library located within the Colored Pencil forum.
Good luck and get out those pencils!
