This pose is for the moment when a sumo wrestler begins to take a four-leg step. Let's draw it with the following points in mind. Is the flow of the large arc of the legs expressed? If you only follow the muscles and joints too closely, you may lose the momentum you want to portray. Is the center of gravity lowered by bending the legs slightly? Are the arms supporting the upper body? It is good if the posture is unstable, but at the same time it gives the impression of solidity.
