>>6855479, while I was able to take that picture without too much effort, there were three tricks. Note how the right arm is missing its forearm armor, I removed to make the arm thiner for that specific arm position to work. Also I adjusted the shoulder double ball joint, to bring the shoulder itself fully forward in relation of the torso. Also I wasn't able to make the folded arms rest naturally on its chest, the arms want to hover, which only looks natural in a hunched back grumpy expression
tl;dr it can arm fold just like in the picture, but it won't look perfect, just like in the picture.
