I went back to my simple dragon model to see what else I can do with it. I didn’t add any detail to the model but I re-folded such that the wings show one side of the paper — the colored or printed side, while the head, body and tail of the dragon show the white or unprinted side. Of course, the reverse can also be done — white wings, printed body.
And I think the challenging part of folding the model is how to make it stand without the bottom part of the tail touching the surface of the table.
