Student-Focused Poster Design Needed

I need a fresh, attention-grabbing poster that speaks directly to students. The goal is to make them pause, read, and act—whether that means attending an event, downloading an app, or simply remembering the brand behind the message.

Here’s what I have so far:
• The overall concept and copy are ready.
• I’ll provide exact brand colours and any mandatory logos or tag-lines the moment we start.

Here’s what I need from you:
• A professionally composed poster sized for both A3 and Instagram Story.
• Clean, high-impact typography and layout choices that feel current to a student crowd.
• Two initial design directions, one round of refinements on the chosen option, and final delivery as print-ready PDF (CMYK, 300 dpi) plus the layered source file (AI or PSD).

I’m open on the visual style, so feel free to suggest modern, playful, or minimalist approaches—whichever you feel best captures student energy. Let me know if you need any other specs before we kick off.
