I love how you used the purple color to be the shadow effect. I think the color works. One thing I would suggest is to add more purple to the darker side of her hair because I think her head goes a little flat on that side because of how dark the paper is. Great job using the soft grays and peach colors to add light to your subject.
I don't know if your friend really has purple hair, but it works so well in your portrait. I'm glad you didn't use black for your shadows, but I think using some dark greens or reds would really mix up the color palette a bit. Maybe adding one shiny hair on shadowed side of her head would keep her hair from getting lost in the background.
Very nice sense of depth! I really enjoy the texture and your color choice. The hair gets a bit stringy, but I like the watery bit in the eyes and the glossiness on the lips.
Great contrast in the skin shading. I like the texture of the skin compared to the strokes of the hair. My only concern is that the lighting of the face and neck suggest a top-down, right-left light source, but the lighting of the hair looks like right-left only (if that makes sense?)
wowers. great highlights in the hair and shadows above the nose. great texture on the face
The hair in this portrait is so much fun to look at! I really like how you rendered the texture, and I like that you paid attention to the way light would hit hair. It looks very realistic!
You're doing a great job making the face and hair texture different! I love how you're choosing different marks - that is working really well! I also think you've done a great job adding more color to her! Keep going! maybe you could do another subtle layer on top and add some more color into the cheeks / undereyes (like a redish, pinkish, maybe?) so its like you can see the blood under her skin. Wow, that was a creepy thing to write... but you know what I mean, right? So she has some warmth in places! You know what i mean! I love the ultra darks - great job pushing the lighting! Maybe you could hit the ends of her eyelashes with a little med grey - ever so slightly on the ends! to pop her eye out of the darkness! Nice job.
