From the Beautiful Women Grayscale Coloring Book by Ava Browne.
I wanted the entire picture to have pastel colors, but then I added red to one of her shirt sleeves, then to her hair and the flowers, so my plans changed, lol.
Grayscale adds the shading for you, but I also put my own dark shading on her face and neck.
I used alcohol brush markers, sparkle pop and milky pop gel pens.
