Modern AI Event Promotion Banners

I’m planning a series of community-focused events and need a set of modern, sleek banners that instantly convey excitement while staying clean and professional. The banners will be used for both print and digital channels—think street-side pull-ups, social media headers, and website hero images—so I’ll need versions in multiple sizes.

Scope & expectations
• Purpose: clear event promotion for local audiences.
• Style direction: modern and sleek—crisp typography, balanced negative space, and a refined color palette that still feels welcoming.
• Deliverables: layered Adobe Illustrator (.ai) files for each banner, plus high-resolution PNG/JPG exports in the common dimensions we confirm together.
• Messaging: I’ll supply event name, dates, and venue details; you’ll organize the copy for maximum visual impact.
• Revisions: initial concept + two rounds of tweaks to fine-tune layout, colors, or copy placement.

Optional but welcome
If you can mock up the designs on real-world signage or social posts, that will help visualize final usage.

Please share relevant banner or poster samples from past work, especially pieces that successfully promoted community or local events.
