Lovely warm hues, and nice detail. One thing that you should watch for though, is the sand that sticks to parts of the body. I noticed that around her bathing suit there is sand stuck on either side... would have been nice for that skin to be unblemished. Other than that, I really like this photo... brings back warm feeling of sitting at the beach. Love that hat, as well!
Nothing can match the original S.I. shot of Christi Brinkly in this pose, but I love the early morning or evening light (the sand suggest the big island of Hawaii which would mean morning light but...) Anyway, colors, contrast, the red suit and hat make this a wonderful rendition. Keeping your horizon light straight is the key and you nailed that!
