Sail Boat Sails Diagram Books Or Websites On Advanced Origami?

Books or websites on advanced Origami? - sail boat sails diagram

Looking for good books, websites and online maps for a medium level. I fold the models of complex problem with no instructions, but you do not know how to design, and nobody seems to explain, for example, the creation of a human figure, etc.

Everything that is what I found on the Internet or in bookstores origami pirate hats and sailboats in 5 steps! : S

Someone knows the resources? Where are all the people who know how to make beautiful patterns in the pictures? And where are the shops?

Thank you! xx
