OK its true I am a groupie I love Pam Carriker's work. She has a unique style which I admire, but promise not to copy. Not only that she explains things so well, and makes it interesting at the same time. I took one online class from her (The Gray series) using just greys pitt pens and I really enjoyed it, learned allot about shading. The video I have the link for is really informative, her picture that she does is so much better than my example. But I did learn allot just from the short video on colour of the face, which I always have trouble with. So go she has a few new videos up and take a look, if you have not seen them before you will become a groupie, I am sure.
