Comparative study of male head sculpts

The rendering depicts a male head and neck, presented in two variations. The primary head is bald with short, dark stubble visible. The man's expression is neutral bordering on serious, with dark eyes and slightly furrowed brows. A secondary head, positioned to the right, displays marginally longer and fuller dark hair, offering a contrast in hairstyle. Both heads are with a uniform, smooth texture and even lighting, lacking visible shading or pronounced anatomical details.
