Every time i have to go through so many versions of poses in order to find the best one. Not so long ago, I started adding a more complex rig for models. It turned out to be a very useful thing for finding a suitable position. But the process is still not fast, because the pose should suit not only me, but also the one who commissioned me to make this model.
It will be necessary to try to do something similar for the selection of poses for ponies.
