I like the vignette you've added in-it's just a little shy of being too visible, while still staying subtle enough to work effectively. With the colors and added snow, it almost looks like a cosplay shoot of a live-action anime. The blurred, out of focus background is a nice touch-it keeps the shot from being too busy. Since the background is out of focus, we're free to focus on the subject- your beautiful model.
yes, she is . and some of it, yes it is real. it can be seen pretty well without adding some in photoshop too, but i wanted to add more to make it feel more "wintery"
