Check the video, her nose on the Ellipse photos are heavily photoshopped. Check the freckle about 2" above and right (her left) of her belly button.
I am unable to paste the link.
The center model does look like Fernanda Prada but her hips and upper thighs look a little bigger than Fernanda's. Thought this might open up some different search avenues. Beginning to suspect this one hasn't modeled since Ellipse and is out of the business.
Found this picture of Leonisa show 2011, center model may be her. Next to her on the right looks like Anahi Gonzales and Caroline Francischini.
Curious if anyone has tried contacting Ellipse directly?
