Don't outline things in black. lol xD
And finally a Lana Del Rey fan yussssssss.
I love your style. I can also see what is going on. Lana in a hat, possibly a dress or shirt and standing or sitting down somewhere looking at the camera at side of her. But the lines are confusing me. Mostly on the shirt/dress. It is also good not to add highlights in the with white. My hair is a super brown hair that looks black in curls, so highlights go in different places. And I have a little sun light with me. And if I hold my hair up, Yes. A tinny bit of white highlights and a tinny bit of highlights in brown a couple shades lighter then my hair. Look at your hair in a mirror or hold it up if it's long and have different light sources and how far or close away the light is to see how it changes the highlights.
When you outline her face take a photo of Lana with the amount of light you saw in the photo and see how her face is shaded and highlighted. Also study the color of her face. Is it mostly pink? Is it mostly yellow? Is it mostly white? And greens can be in the skin (I believe so, I don't remember)
Great photo though biggrin
