Architectural realistic watercolor city elegance

Create a vertical city poster showing the process of transitioning from watercolor painting to realistic photography. Canvas is vertical, ratio about 4:5, presenting a seamless transition from left to right: the left half is an expressive watercolor illustration, retaining visible paper texture and paint splatter edges, using soft tones of blue, lavender, peach, yellow, and cyan; the right half gradually transitions to a clear, realistic aerial photograph of the city under a bright blue sky with sparse clouds. The skyline must include the landmark buildings of Beijing CBD: the towering CITIC Tower on the right, the CCTV Headquarters (Big Pants) on the middle right, and multiple glass skyscrapers in the left-middle, with wide roads, lanes, trees, low-rise buildings, and city avenues visible below. Add an elegant Chinese font title at the upper left, below it a thin horizontal dividing line, and a smaller subtitle . Use warm afternoon sunlight, rich realistic details on the realistic side, and a dreamy translucent watercolor wash effect on the painting side, making the boundary between painting and reality poetic and fluid, as if the city is awakening from a scroll. No people in the image, no watermark, no extra labels.
