Outstanding. And here's a tip illustrated in this photo: rather than have a model face the camera straight on (especially a petite one), if she twists at the waist she looks thinner. In this photo, her hips are almost a side profile but her upper is twisting towards the camera. It's a "thinning" pose that works well for petite models (where they'll look heaving facing the camera directly rather than at an angle), or women with a stomach issue.
And...red is a dynamite color for her given her hair color. And I like how you had her right arm apart from her body. If it was next to her body is makes her appear heavier--adds 5 pounds. That separation is a good touch.
