William, brave effort for both you and your model! (girlfriend/wife?) Try the same idea with window light during the daytime. I don't mean direct sunlight streaming into a window, but a north window (in the northern hemissphere) or on an overcast day. It's the lighting that needs tweaking in these portraits. It is amazing the effect different light has on the final outcome. In fact, it is the lighting that has almost all the influence on the final outcome! Keep it up William, keep it going, experiment with light!
