I love the pose and I think that you look gorgeous. I really love the colors, too. The one thing I would change--the cropping. A couple of important rules are: -Don't leave a lot of space above the subject in a portrait -Don't place subjects in the center
Having said that, I think that you should crop it from the top (leave just a little bit of room above the wrist). Then crop it from the right (again, leaving a little bit of room to the right of your shoulder blade). One more, crop it from the bottom (leave a little bit of room under the elbow--and it's okay if the necklace is cut off in the photo, I think that that makes it more interesting).
