I have Hela for sale. I have her up on FB sales post or you can message me here. I never displayed her, only inspected the figure, and she's been in the box for nearly 5 years.
It's basically the IW headsculpt, with short hair. All the facial details are almost exactly in the same spots as the IW sculpt. They may have made tiny adjustments, but I doubt this a completely new sculpt.
Quick photoshop, I'm going to paint over the costume something like this. And I'm going to switch out the head for a more comic looking one, I hate the emo hair.
