My Love WIP

Ok so this is another important one to me.. Self portraits aren't my specialty but I gave it a shot anyway.. This is a portrait of my girl friend.. Here's the reference pic: Link Any help or suggestions is much appreciated.. Im thinking of doing some flowers in the back ground.. I want them to be yellow as the complementary color but I don't think you'll be able to see them well so maybe blue..
