The legs do seem out of proportion for the ESB one, but I think it may just be because it's posed a lot taller than the Bandai 144 kit and the studio profile photo of it. In those photos, that lower link is closer to 45 degrees and the upper link is near horizontal. Was this needed to fit it into the case? Does this model include the inner link between the "thigh" and "torso"? If so, is it a pair of ball joints?
