Keeper of Secrets - Shalaxi Hellbane vs Bloodthirster

"The Keeper of Secrets known as Shalaxi Hellbane is a peerless hunter whose favoured prey is nothing less than the greatest champions of the other Dark Gods."

Here you can see two versions of the same picture. I prefer the first version. The Keeper of Secrets looks more powerful in that one. But the official image is the second one. Which one do you prefer?
