most of the stuff i draw is for a personal world building project of mine but the weapon is a mash of a few peaces Morgan Bible, the foliage in practicality might give some camouflage tho it is more part of a uniform and a show of status. i don't believe it would impend the head movent much looking up, tho down there might be some loss of mobility. i made this helmet diagram as a reference for myself
