Architecture realistic hand-drawn vintage elegant

Create a 9:16 vertical digital surrealist architectural vintage collage, with a background of warm cream textured paper with subtle grain, stains, and aged print speckles. At the center of the composition is a huge gray concrete arch, with two thick vertical legs and a rounded arch top, presenting a realistic brutalist texture with air holes and chips. Behind the arch, place a huge soft red-orange circle, partially obscured by the arch, like a flat sun or a hand-painted paper plate. In front of the arch, slightly left of center, vertically suspend a classical plaster column fragment, including capital and base, presenting an unsupported floating feel. Add 4 floating concrete cubes: a large cube near the upper right corner, a small cube to its lower left, a tiny cube in the lower left corner, and a medium-sized cube near the lower left edge. Add 1 irregular broken concrete rock fragment in the lower left corner. Add 6 birds flying from the right side of the arch toward the upper right area, rendered in a vintage paper-cut swallow style with dark wings and cream-colored bellies. Include abstract drawing marks: dashed construction lines, a rectangular grid behind the upper left of the arch, a thin circular target line on the right, a dashed diagonal guide line on the left, and faint horizontal and vertical alignment lines spanning the collage. Overlay torn-paper shapes at the bottom: a beige textured paper scrap beneath the left arch leg, an olive-green torn paper patch behind the right leg, and an ochre-yellow vertical block with rough brushstroke edges in front of the lower-right leg. Use a restrained palette: , , , olive green, ochre yellow, and charcoal gray drawing lines. Maintain a mixed-media vintage editorial collage style, surreal and elegant, with ample blank space around the central object, no typography, no border, no watermark.
