Very cute pic. The facial expression, and the eyes, portray very innocent and carefree emotion quite well, and the motion on the blanket adds a nice touch to it (like also the designs on the blanket).
I like these types of interpretations. That is, of Luna having generally a carefree and happy childhood. It makes her more multidimensional (possibly the type trying now to rediscover an element of that which may have gotten lost while growing up).
