Instagram Product Promotion Poster Design

I need a striking poster, optimised specifically for Instagram, that will persuade viewers to try our product. The visual must be feed-ready (1080 × 1080 px preferred), scroll-stopping, and consistent with our current brand colours and typography, which I’ll share once we get started...
