Event Promotion Poster Design

I’m preparing an event and want a striking poster that instantly communicates what’s happening and persuades people to attend. The job is pure graphic design: translate the event’s mood, key details, and branding into a visually compelling, print-ready poster.

Here’s what I’ll supply once we start:
• Event name, date, and venue
• Logo files and preferred colour palette (if any)
• Reference images or style examples I like

What I need back from you:
• A poster concept that grabs attention in both digital feeds and on physical boards
• Final artwork in high-resolution PDF for print and a layered source file (AI or PSD) so I can make small edits later
• Web-optimised JPEG/PNG for online sharing

Please include a brief note on how you’d approach layout, typography, and imagery for an event promotion piece. If you’ve tackled similar posters before, a quick link or two would help me gauge fit. Looking forward to seeing your ideas come to life.
