Very nice portraits, it's good to see ladies looking natural and not heavily made up. I shoot portraits on Fuji Provia 100F all the time the skin tone rendition is excellent about the best currently available in a slide film, very well done.
That red dress against the steel grey of the sea really makes the picture "pop", but I feel that if these pictures were shot from a slightly lower angle the horizon would be in a better place around her shoulders rather than half way down her head, but they are still very good pictures.
