Is that a ghost/spirit?

That's a half ghost.

Myon has proved to be useful in many ways..

Does anyone else see the strange leg/hip joint positioning, there? It's like ler right leg is connected to her abdomen, rather than her hip. The crotch lines are a good distance away from where they should be.

Your call, guys. Error tag?

It's less noticeable because it's obscured by Myon, but yeah, it looks weird to me too. I agree with you on this one; looks like an error to me.

Aww. That kinda ruined it for me because now I can't unsee it. :(
