Different
So this was different as you can feel something coming off those shading details with your shadows. It feels almost like you have this women inside a rain storm or some kind of natural occurrence but you have a nice idea here and it shows some great shading work and represented very well here a use of black and white. I do find a border with this type of black and white work would do you well, and perhaps next time adding some color to just one element on the face (lips or eyes) to bring a pop of interest with color.

Just a border and maybe a splash of color
