A cinematic transformation video that starts with a hand-drawn architectural sketch on white paper, created with blue and green pen lines. The sketch shows a corner building with classical arched windows, balconies, and strong vertical lines, viewed from a low-angle street perspective. As the video progresses, the sketch gradually transforms into a realistic building: Pen lines slowly glow, solidify, and morph into real architectural materials Paper texture fades away into stone, glass, and painted façades Blue and green sketch strokes become deep green walls with cream trim Windows gain depth, reflections, and warm interior lighting The environment evolves into a modern city street at evening: The sky darkens into a cloudy blue dusk Light rain begins falling, creating wet reflections on the street City buildings softly appear in the background People walk past holding umbrellas, silhouettes moving naturally Streetlights and interior lights turn on, adding a warm cinematic glow The transformation is smooth, magical, and realistic, preserving the original angle, proportions, and architectural style of the sketch. Ultra-realistic lighting, shallow depth of field, cinematic camera movement, slow reveal, 4K quality, photorealistic, dramatic mood.
