>>8369800I don't know how trivial this will be to you, but notice how each body part typically has a ball joint that incudes three independent rotations, providing three axes of rotation for the piece.
For some pieces, you can handle them kinda intuitively, since the joint is arranged in such a way that one of the parts of the joint will always respond to your movement. For example the best way to make the final balance of a figure is to use your hand to firmly plant the foot on the ground, then use your other hand to rotate the chunk of the rest of the figure at the ankle so that the ankle joint finds its way until the figure is balanced. The shoulder is another example of joint that will give you no problems.
Skeleton figures tend to have annoying spine joints, though, and this will be your bane until you get a hang on them. Problem with these joints is that the top and the bottom have to be somewhat coaxial, so if you want to bend the spine in a given direction you will have to consciously work on each of the three joint rotations independently. You have to know what pose you want beforehand. Try to practice a few poses giving your skeletons some hip sway and shit.
>>8369873Yeah, I would think that this was a line that could continue for a long time since you may always want to buy more basic skeletons and accesories. I used to combine a couple of them with each order I made on amiami and I basically could see myself buying them for like forever.
