I don't think so, to me it seems just right. The legs are just a little longer then they're upped bodies. The guy seems like an orc so it wouldn't matter that much and the woman has her legs bent making them seem shorter. I think its perfect.
I like the powerful up shot you used on him. Very effective at adding to his sense of power.
I'll say this though, the girl doesn't compare to him. She looks like an afterthought, added later. He has depth and weight, exists in his world. She, although having dimension, feels 2D in reference to him. Especially in her torso and thigh. Hope that helps.
It is a killer piece of work, don't get me wrong. Very detailed and perfectly lit. Much respect, bro.
