Tranh Ghép Vintage Kiến Trúc Thô Mộc Siêu Thực

Vertical 9:16 digital surrealist architectural vintage collage on a [warm cream] textured paper background with subtle grain, stains, and aged print speckles. Center the composition around a monumental [gray concrete] arch with two thick vertical legs and a rounded top, realistic brutalist texture with pores and chipped edges. Behind it, place one large [muted red-orange] circle partially obscured by the arch, resembling a flat painted paper disk. Suspend a single classical plaster column fragment vertically in front of the arch, slightly left of center, floating without support. Include exactly four floating concrete cubes: one large cube near the upper right, one small cube below-left of it, one tiny cube at lower left, and one medium cube near the lower-left bottom edge. Add one irregular broken concrete rock fragment at the lower left. Feature six cutout-style swallow birds with dark wings and cream bellies flying from the right side of the arch toward the upper right. Layer abstract charcoal drafting marks: dotted construction lines, a rectangular grid behind the upper-left arch, thin circular target lines on the right, a dotted diagonal guide on the left, and faint alignment lines. At the bottom, arrange torn paper elements: a beige textured scrap under the left arch leg, an olive-green torn patch behind the right leg, and an ochre-yellow vertical paint swatch with rough brush edges in front of the lower right leg. Palette of [warm cream], [muted red-orange], [gray concrete], olive green, ochre yellow, and charcoal drafting lines. Mixed-media vintage editorial collage style, surreal, elegant, generous negative space, no typography, no frames, no watermarks.
