Something I might actually use... Tried again.

The interesting thing is that the pose of the larger one is almost a perfect re-scaling of the smaller one. Of course, with a few edits to embody the difference in size, but they more or less overlap neatly, which is why I'm having trouble seeing why it's unnatural. It's definitely to do with the legs and feet, but I can't for the life of me tell WHAT about them...
