I think that might be a little of the blur effect of the moving blade in that shot... but yes, the Hasbro is a bit oversized... but not too bad really. Within reason. A larger body with larger hands would certainly help.
I wouldn't want to use a Comedian or Whiplash or T-800 body for this guy (too pricey) but that would really add the size you need. Of course, the sculpt being on the small side already causes problems. Fortunately the turban can help hide that to some degree.
A tall buck would be fine for this height-wise. I have some old 21st Century bodies that might even work with a bit of the knee extension.
I'm not too concerned about what's unseen on this guy. Just want to get the height right, the tunic length right, replace the sash and repaint that sword. This bash is even simpler than Sallah if you're OK with the Hasbro parts. It's basically a body swap.
