armored helmet 3d model

Generate a hard-surface armored helmet model based on the provided image. This is NOT a biological skull. This is a rigid mechanical helmet. Critical proportion requirements: - The lower jaw and lower face must be WIDE and outward. - The lower face width should be comparable to the cheekbone width. - Do NOT taper the jaw inward. - The face silhouette should form a strong trapezoid shape, not a triangle. Mouth and chin: - The mouth is a solid armored faceplate with engraved horizontal grooves. - No individual teeth geometry. - No jaw separation. - No mouth opening. - The chin is a thick, load-bearing armor block and must extend outward. Cheek and jaw relationship: - Cheekbones and lower jaw connect as a continuous armored plane. - No skeletal hollows or concave transitions. - The lower face must NOT appear narrow or recessed. Nose and mid-face: - The nose area is solid metal with shallow recesses. - No hollow nasal cavity. - Treat the nose as part of a rigid armor mask. Modeling priority: - Correct overa
