Learning to draw Realistic faces

I'm taking Suzi Blu's on-line class Goddess and the Poet. This is the first drawing I have done and I'm pretty pleased with myself, but it looks like hers, so I want to play around with spaces and distances between features and maybe come up with a face I can call my own. Still it's a pretty face and I think I got the shading right. Now on to using color with colored pencils which are new to me, too.
