photorealistic digital painting, elderly Siberian hunter with deeply weathered face and thick grey beard dusted with frost, wearing a worn sheepskin ushanka with frayed earflaps and a coarse crimson rubakha stained with dried pine resin, cradling a trembling terrier puppy with matted russet fur against his chest, standing in a dense birch forest at golden hour, slanted amber light piercing through skeletal branches casting long distorted shadows across moss-covered bark textures, volumetric mist curling around gnarled roots, hyperdetailed skin pores and fabric weave, cinematic chiaroscuro lighting, 8k resolution
