Would you like to come up and see my etchings?

Skin is hard... I'd use less of the cool color, especially when it seems you're using similar hue for both the background and your skin. That kind of flattens the image. If you're still working on this portrait, try darkening the bg more, and don't paint the eyes until the very last. Use a bigger brush if you have one for laying out the body/shirt part.
