Disney-Pixar style illustration, 16:9. Split-frame comparison of the same young woman with expressive brown eyes and long chestnut hair. Left side: tired expression, slouched posture, dim lighting, labeled "Day 1". Right side: same woman glowing with energy, confident bright smile, upright posture, warm golden lighting, labeled "Day 7". Sparkling light particles transitioning between the two sides. Focus on mood, energy and confidence rather than body shape. Cozy, motivational atmosphere.
