AI-Generated Poster Design for Large Printing

I’m looking for an experienced graphic designer or digital artist to recreate, refine, and prepare three existing AI-generated poster images for professional printing at 24 × 36 inches. These are not original hand-created artworks. I will provide the approved PNG files, and the goal is to preserve their existing designs while improving the resolution, details, and print quality. The posters feature: A young boy astronaut A young girl astronaut The brother and sister together All three use the same retro sci-fi style, Cuban imagery, vintage typography, rocket, planets, and distressed poster texture. Scope of Work Recreate or professionally upscale all three posters Preserve the characters, faces, typography, Cuban flags, rocket, colors, and composition Correct AI and upscaling artifacts around faces, hair, helmets, lettering, flags, suits, and rocket details Rebuild typography cleanly where needed Prepare each poster at 24 × 36 inches, 300 PPI Target approximately 7200 × 10,800 pixels Add bleed according to the printer’s requirements Prepare files using the appropriate print color profile Do not simply enlarge the source files without manual cleanup Deliverables For each poster: Print-ready PDF High-resolution TIFF or PNG Layered, editable PSD Reduced-resolution proof for approval Detail proofs of the faces, headline, Cuban flag, and rocket
