First and foremost, the feeling of this photo is fantastical. Because the head and face are not shown, it leaves more to the imagination of the viewer.
The red polka dotted pattern draws you in; and the simplicity of the positioning of the hands and legs sets the photo just right. The ring, the bracelet, even the birthmarks and freckles give the piece a feeling of being "real" yet it's not overwhelming.
I gave 3.5 stars for originality because the position itself is not so different from other things I've seen. It's the subtleties that set it apart from the rest.
Fantastic job all around. Keep doing what you're doing, it works!
