Guenevere step-by-step

I got a lot of positive feedback about the last step-by-step image that I submitted, so I've made another. Hopefully this also eliminates any doubt that my work is traced or a paintover.

Photoshop 6.0. Wacom. Airbrush (default round hard edge brushes) and eraser only. I think its easier to paint without the smude tool, dodge or burn. No tracing, paintovers, or filters.

Thanks to Satyrgirl [link] for allowing me to use her IvyLady shot as a photo-ref. The photo is here: [link]

steps:
1-3: the sketch, and different adjustments that I tried. Drawn from photo-ref with no tracing. 1pixel brush, 100% opacity in a single layer.
4: Basic colors and shading
5-6: Building up skintones with shading and highlights
7: Shading and highlights for nose and mouth
8: Starting the detail work on the facial features
9: Basic highlights in hair
10: Suggesting major chunks of hair
11: Adding more contrast to suggest smaller strands
12: Adding single hairs
