3D Origami Collection Fantasia de Papel

Here is a fabulous 3D Origami Collection by Fantasia de Papel. All of her artwork is really good… but the one thing I would like to know is how she makes the legs of the Chicken Little and the boy with the hat.  It’s amazing how she makes the two separate limbs and some how makes it all come together.  If anyone knows how this is done PLEASE let me know.  Thanks!!
