Maybe a bit more distinct creases, as they look a bit soft, but dunno, that sorta soft bonemold look does seem to be a part of early crusader style too. So maybe disregard that.
One thing I'd definitely make sure to test in your test prints though are the difficulty of installing a visor. Some of your sunken cheeks are quite close to the visor edge, which may make mounting a visor difficult for both to much compound curvature that will make installing a single curve visor plane difficult, and just lack of space for installation mounts.
But yeah, looks amazing. I really like those brow ones, reminds me of the headbands historical crusaders would wear on their helmets.
