The crooked witch, designed by Andrew Hudson of Origami Weekly, is a good design to fold, provided you have the right double sided paper with the right colours. Orange-Black, Green-Black look good for this one.
Sorry about the bad photography. I was not able to get rid of that glare no matter what I did!
