POP COLOR URBAN CUTOUT - 都市旅行照片重绘

Create a vertical 3:4 before-and-after travel re-illustration in the style of [POP COLOR URBAN CUTOUT｜波普彩色城市切片风]. The composition is strictly divided horizontally at the exact center: the upper half retains the input city travel photo, preserving the original composition, landmarks, perspective, and main figures, with only light editorial color grading; the lower half re-illustrates the same scene, maintaining the same viewpoint, landmark outlines, road directions, and recognizable city elements. The lower half uses large interlocking colored paper-cut shapes, simplified building silhouettes, stepped edges, bold yet controlled urban color blocks, screen-print grain, and a few halftone dots. The palette is extracted from the original photo and the city's character, without applying a fixed rainbow filter; dark outlines stabilize the architectural structure, while high-saturation primary colors strengthen streets, vehicles, sky, and landmarks. Details are compressed into orderly geometric color planes, preserving the city's narrative and spatial depth. The upper and lower halves must correspond one-to-one; no multi-panel collage, no shifting of landmark positions, and no random omissions, misalignments, or rearrangements. Only a clean horizontal dividing line separates the two halves; no titles, labels, logos, watermarks, AI badges, or original image corner marks are added. The lower half must not contain photographic texture, smooth gradients, 3D rendering, chaotic glitches, pure filter effects, or unreadable text.
