Nguyen Hung Cuong, a paper artist in Hanoi, folds paper into elaborate origami designs of animals, insects or fish, using only a single sheet of paper. Many of his creations feature intricate details, like ears, gills, complex pincers, and roaring mouths. Some of his most challenging creations, such as his piece of a winged horse, a scorpion fighting a snake, or a shark mounting waves, took him months to prepare.
