Ah be nice Chrono. It says you wish for critique so here you are: it looks like you tried to outline the face, that's fine if you wish to draw a cartoon, but the face looks uneven. Your shading is almost on track, but there isn't a consistency of light throughout the picture, when working with shadow, you want consistency to give it that realism. You did a great job with the hair and the parts of the face look well blended in, the nose is a little off with the lining of the mouth. If you were to ask me, does this look like Jenna Jameson? I would have to say no. not trying to be mean, but just giving my artistic opinion.
