For such an innocent-looking lady, there are a deceptively high number of piercings in this portrait. Note the nose stud and eyebrow piercings - the ears are hidden, but one can presume that there are some more there.
I'm not overly happy with some of the detail in this one, but I like the model and I find working with redheads gives the portrait much more saturation and colour intensity - far better than a sea of lifeless brunettes.
