What is the most complex origami in the world?

If you're a fan of origami art, you might have wondered what is the hardest origami model in the world? In my opinion, the record now should be Dueling Knights. The record was the Origami Ancient Dragon which was designed by Satoshi Kamiya and it took approximately 16 hours of work to finish.

The designer of the model has spent 2,5 years to design it, and it took him about109 hours of folding to make the origami. Hell yeah, you've heard it right, 109 hours which are way longer than the Ancient Dragon origami that I mentioned above.
