lol, guessing you missed the last 20 pages of debate over the PF's divergences from the Dynamite #53b cover art. This Savage cover has more of a victory pose, Sonya's stance more upright with her looking upward and her sword off to her right like the PF- something a lot of people seemed upset about (that it was changed from the cover). I haven't read the entirety of the comic, but the PF and that second cover are the only places so far I've seen that particular sword, and both bloodied- I could be wrong though
I would guess the designer studied all the cover art with Sonya holding a severed head and took bits from each
