I find that making creases where the black lines are is helpful.
Seriously, the basic model is divided into 1/3rs. It is essentially two water-bomb bases with strip grafts fashioned around it. Not all the creases for the head are shown on this model.
Once you collapse the aforementioned water bombs, look for four quarter frog bases in middle of the square edges. These form the wing edges, the leg edges and the neck. One you fold these units, the rest of the model starts to fold itself.
I once set up an origami PLC. But the business folded.
