Surrealist Architectural Vintage Collage

Create a 9:16 vertical digital surrealist architectural retro collage with a warm cream-colored textured paper background featuring fine grains, stains, and aged printing spots. At the center of the composition is a large gray concrete arch with two robust vertical legs and a domed top, exhibiting a realistic, Brutalist texture with air pockets and gaps. Behind the arch, place a large, soft reddish-orange circle, partially obscured by the arch, resembling a flat sun or a hand-drawn paper plate. In front of the arch, slightly to the left center, vertically suspend a fragment of a classical plaster column, including the capital and base, creating a sense of unsupported suspension. Add four suspended concrete cubes: a large cube near the upper right corner, a small cube to its lower left, a miniature cube in the lower left corner, and a medium-sized cube near the lower left edge. Add one irregular, broken concrete rock fragment in the lower left corner. Add six birds flying from the right side of the arch towards the upper right area, presented in a retro paper-cut swallow style with dark wings and cream bellies. Includes abstract drawing markers: dashed construction lines, a rectangular grid behind the upper left of the arch, a thin circular aiming 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 below the left arch leg, an olive green torn paper patch behind the right leg, and an ochre-yellow vertical block with rough brushstrokes in front of the lower right leg. Uses a restrained color palette:{argument name="background paper color" default="Warm cream color"} ,{argument name="main circle color" default="Soft reddish orange"} ,{argument name="architecture material" default="gray concrete"} Olive green, ochre yellow, and charcoal gray drawing lines. Maintaining a mixed-media retro edited collage style, surreal and elegant, with ample white space around the central object, no typography, no borders, and no watermarks.
