The art aesthetic was mostly in keeping with the original style of each hero (though not their design), but I found it sort of amusing that the positions were unchanged, which is why that’s what it reminded me of.
In some cases some portions were redrawn a bit, like Bane’s arms being redrawn bare, or Boldtusk’s hands being exposed.
You can get a sense of what I mean by looking at Boldtusk and Quintus from the sneak peek, and comparing their positions and faces to the originals.
