Striking.

This striking high key portrait is especially effective due to the dark hair of the model which separates her face from the background. Her skin tone is perfect. I don't know if this is in the original or from manipulation in Photoshop, but either way it is great. You did not do as many portrait creators do, namely over-use Photoshop to eliminate every mole or wrinkle (not that she has any wrinkles). You can actually see her pores by your use of F/5. I think that this is great because less is often more, as it is here. I like the way you placed your lights level with her face on each side for very even lighting. By the way your model is lovely. This is a beautiful portrait, very well done!
