The pencil copies by Yulian Zaiats reproduce two portraits that differ in time and style, preserving their composition, character, and expressiveness, but translating their colour and texture into monochrome graphics. The first copy is a pastel portrait of Voltaire (1735) by Maurice Quentin de La Tour. In the original, the soft light and velvety texture of the pastel, along with the subtle play of halftones, emphasise the intellectual acuity and ironic expression of the philosopher's face. In Y. Zaiats' version, these nuances are conveyed by subtle gradations of strokes, smooth transitions of light and shadow, and delicate modelling of facial features. The characteristic posture of the head, the gaze, and the barely noticeable smile have been preserved, giving the portrait liveliness and recognisability. The second copy is a portrait of the sculptor Jakob Bradl by Leo Samberger. The original is distinguished by its restrained but expressive colour scheme and attention to the plasticity of the face, which conveys the model's inner concentration. The graphic reproduction preserves the clear outline of the form, the emphasis on chiaroscuro contrast, and the texture of the hair. The hatching structure enhances the sense of sculpturality, echoing the creative profession of the sitter.
