I have finally finished this painting! I was going to add more detail to the hair but realized that I wanted the focus to be the eyes and adding detail in other places would draw attention to it. So the hair is more loosely painted. I also am cropping a few inches off the bottom to better balance the portrait. Less is more and things shouldn't be added just because they are in the reference image. An artist needs to ask themselves if inclusion helps or lessens the overall look they were trying for.
I will add the drawing stage of the next painting as soon as I have it started after I work this weekend.
