Digital Product Promotion Poster Design

I’m preparing to launch a new digital product and need a striking promotional poster that immediately tells potential buyers what makes it worth their attention. The format is a single-page poster—no carousel or multi-slide layout—sized for both social-media sharing and standard A3 printing so I can use the same design online and offline.

Key points I’ll provide once we start:
• Product name, tagline, and brand colours
• Any screenshots or mock-ups that must appear
• The core call-to-action and landing-page URL

Your task is to translate that material into a clean, eye-catching composition. Please deliver:
1. The final poster in high-resolution PDF and PNG (300 dpi).
2. The editable source file (PSD, AI, or layered Figma—whichever you prefer).

I value clarity, modern typography, and intelligent use of negative space, but I’m open to your creative suggestions as long as the finished piece speaks “premium digital product.” Turnaround of two to three days is ideal; let me know if you need anything else from my side to hit that timeline.
