Oksana Tkachuk提示Realistic portrait of a young Slavic man, 21 years old, with fair complexion and short light brown hair styled naturally. He's wearing casual modern streetwear - perhaps a comfortable hoodie or casual jacket. A backpack is casually slung over one shoulder, suggesting he's a student or young professional on the go. His expression is energetic and curious, with bright, engaging eyes that convey youthfulness and intelligence. The background is clean and modern, perhaps a subtle gradient or minimalist urban setting that doesn't distract from the subject. The overall mood captures the vibrant, optimistic energy of youth with authentic, natural lighting that enhances his features. Professional portrait photography style with sharp focus on facial details and natural skin texture.
