Hello Debra:
I might recommend removing the light flare around the head and going with a background that is more indicative of a natural setting - i.e., a solid color or a gradation that you would find in nature - top to bottom, bottom to top, etc. The light flare around the head is a tool of photographers and suggests "photo" rather than "painting".
It really is great work for a three-hour session. I am amazed!
