I like how you have placed her over to the right with part of her face out of the frame. And then with part of the top of her head out also, this positioning seems to support her shy expression. Her ponytail extends out into the space to her right and becomes OoF background while completing the idea of "sweetness." Masterful work!
When you see an image like this overexposed ... you wonder why there is anything wrong with overexposing an image in the first place, glad it did well for you.
