Edit this poster, combining its vintage recruitment-print aesthetic with deliberate retro digital dithering. Two essential changes: (1) Redraw the central pointing man's shoulder and entire pointing arm with convincing anatomy. Show an unbroken, clearly readable jacket sleeve from his right shoulder (viewer left), through the upper arm and bent elbow, to a shirt cuff at the wrist and the foreshortened pointing hand. The shoulder must have natural width and connect to his torso; no floating forearm, no bare forearm emerging from nowhere, no disconnected sleeve. Preserve his recognisable face, moustache and direct gaze, and the iconic pointing gesture, but adjust arm size and pose as needed for believable anatomy. (2) Fill the currently empty upper/middle left background with ONE cohesive graphic field of retro computer imagery rendered in coarse ordered dithering: a restrained olive/charcoal architectural silhouette of a server cabinet dissolving into square pixels and stepped Bayer-dither gradients, with a few subtle orthogonal circuit/data paths. It should balance the visual weight of Westminster on the right without becoming a collage of separate props. Medium density, visible square pixel pattern, broad graphic shapes, strongest at the left edge and fading toward the figure, legible silhouette around his shoulder. Carry a little of this digital dither into the edges of the jacket and existing computers to blend old lithography with early computer graphics. Keep the lower-right collaborating programmers and their screens, Westminster, cream paper and rust red typography, border and portrait aspect ratio. Preserve exact text YOUR COUNTRY at top and NEEDS BUILDERS at bottom. Keep face and hands carefully drawn rather than pixel-obscured. No neon, floating holograms, robots, extra people, extra slogans or extra banks of monitors. The result should feel like a beautifully designed vintage civic recruitment poster remixed by a digital artist, with balanced density across both sides.
