[@Rithy] can't argue with that though it's a very cool helm.

 If you want to go to the more sexy and disturbing look. Make the helmet look like it is really a face. With eyes, nose, mouth, everything. And work to give the disturbing things using that as base. aybe have a decorative blindfold of spiky materia that has decorative blood dripping as if it pierces teh eyes. Or the face is slightly deformed as if ravaged by tentacles from underneath the skin.
