Amit, this was my favorite of the images you posted, but I felt it could use a bit of cropping and intensifying of the color. I used the rubber stamp with an airbrush at light opacity to partially cover overexposed highlights, darkened the lips, lightened the pupils and whites of the eye. Used buZZ layer beneath an original duplicated and then a layer mask to bring the skin through so it would be smoothed out a bit. Used curves to increase contrast and saturation. Sharpened a bit. Update: I agree with Amit's post that the hair has lost it's luster. It could be fixed by placing this image over the original and using a layer mask to paint through the hair from the original.
