Cuttlefish (M. Arispe Guzman)
Design : Marcelo Arispe Guzman
Paper : One uncut square, Double tissue, 22*22cm
International Origami Internet Olympiad 2018
Round 2 - Task 01
The original design looks more like a squid than a cuttlefish.
I tried to correct that "flaw", by rounding the belly and giving the membrane around it a more floating aspect.
The result looks great, albeit too flat for my liking...
