What book after prehistoric origami?

[crumpybumpy]

I am relatively new to paper folding. I just about finished Montroll's "Prehistoric Origami" (still have to do the Steg). I learned a lot from this book and would like to continue within this difficulty level and/or a litttle more challenging. (I do want to take a break from dinosaurs )

What book(s) would you recommend after this one for learning and similar or slightly harder difficulty level?

Origami Sea Life is worth checking out. It has some very simple models, but a lot of high-intermediate and complex ones. They are challenging, but not too challenging and range over a variety of difficulties. It is probably my favorite book.

I agree with Johnnycakes. If you don't mind some models from rectangles, triangles, etc and want to learn wetfolding, I'd also recommend David Brill's Brilliant Origami.
