A3 Poster mockups, generated — not templated

A3 is a common size for event flyers scaled up into posters, so a designer wants a realistic sense of how the smaller format reads once it's actually pinned to a wall. A quick mockup shows whether the design still holds visual weight at that size.

Photorealistic studio product photo of a small 3mL glass pharmaceutical vial with a clear glass body. The neck has a silver aluminum crimp cap band, topped with an amber-orange (hex D6810C) flip-off plastic disc cap. A rubber stopper sits fully seated and hidden beneath the crimp cap — no rubber visible sticking out above or around the metal. Only a small amount of loose white lyophilized powder dusting the bottom of the vial — the vial should look mostly empty, not filled or packed. Use my uploaded label image exactly as provided, pixel-for-pixel — do not regenerate, redesign, or reword any part of it. Vial centered, shot straight-on, soft even studio lighting, subtle soft shadow beneath, plain flat warm off-white background (hex FBF8F1), no border, no frame, no card, no rounded corner mat, no vignette — the vial floats on a plain background with no outline around the photo. Minimal reflections, sharp focus on the label. No other objects, no hands, no props. Make the e label take up the majority of the vial like in the second picture. Make the label the same size as the one in the second picture

Photorealistic studio product photo of a small 3mL glass pharmaceutical vial with a clear glass body. The neck has a plain gray aluminum crimp cap with a matching gray flip-off top — uniform gray/silver, no colored accent. A rubber stopper sits fully seated and hidden beneath the crimp cap — no rubber visible sticking out above or around the metal. Inside the vial, a solid white freeze-dried lyophilized cake sits at the bottom — a dry, compact, slightly porous solid plug of powder, not loose scattered granules, filling roughly the bottom quarter of the vial. The label wraps the vial and extends down close to the base, leaving only a small strip of bare glass visible at the neck/shoulder above the label — similar to standard commercial peptide vial labeling.
