A brighter 'catch light in her dark eye, would have really helped this image, but as is, her dark eye is almost dead.
Next time be on the look out for this missing factor, it's important, especially seeing the bright white under eye, which is missing in the other eye, makes the weak catch light all the more important.
Also, when you do print this, consider burning in the solo fabric fold on her darkside, so it simply becomes part of the 'Dark' and more mysterious.
@eli griggs Thinking about it even more, I guess the rule of thumb should be either leave that side totally dark or at least have a noticeable catch light.
