The great thing about this portrait is that you have taken it out of its context and made it more real, more warm and more human. You've made it a powerful portrait of female sensuality. She is here the kind of woman that you covet for her strength. Her face still has the sense of tenderness but also a sense of full ability to bend the world to her whim. She says here,"I will so not take s**t." and would kick the ass of anyone that would try to possess her. This is an image that transcends!
Nice!~~~ Different photos really make a painting look so different. Her skin tone looks a lot warmer... but I guess you did not even change her skin tone. I can feel the sense of romance now.
