Yesterday I met up with Stephan Weber, who is a great advocator of expressive folding. At the end of the night we folded his bull, although I have to admit I couldn't replicate it again now. It's easy to see that Stephan has a lot of experience with folding, as he confidently and quickly makes the paper do exactly what he wants it to. With a bit of practice I hope I'll learn a bit of his shaping techniques, although I have to admit I still love having reference points. But if one could combine the exact placement of folds through references, and the combination of curved and straight folds that Stephan facilitates, I think origami works could be taken to another level.
And, as a disclaimer, of course this model isn't folded as nicely as it should be. It was a test fold, and time was limited. You can see at several points (e.g. the hooves) that with more time and practice they can be shaped quite nicely. And of course the proportions aren't quite there yet.
