A fit, lean man positioned tightly in the right part of the frame, shown from the chest up, shirtless and confidently flexing his bicep with his arm slightly lowered for a natural, relaxed pose. He is surrounded by a vibrant green glowing aura softly emanating from his body. The background depicts a winter night forest filled with blue fir trees under a starry sky. Snow gently falls from the sky, with some snowflakes resting lightly on his skin and hair, enhancing the cold, serene atmosphere. The dark, snowy setting contrasts beautifully with the bright green aura around the man. The scene features sharp, high-contrast lighting that highlights his muscle tone and facial features. The composition is bold, dynamic, and designed as an eye-catching YouTube thumbnail.
