Modern Vibrant Art Poster Design

I’m putting together a decorative wall poster and want it to feel unmistakably modern, bursting with bright, energetic colours. The finished piece should stand alone as artwork—no event details, taglines, or product messaging—just a striking, contemporary composition ready to print and frame.

Here’s what I need from you:
• A high-resolution print-ready file (minimum 300 dpi) in both PDF and PNG formats
• The layered source file (Adobe Illustrator or Photoshop) so colours and elements remain editable
• Sizing that scales cleanly up to 24" × 36" without loss of quality

Bold geometry, smooth gradients, playful contrasts—anything that delivers a fresh, modern vibe is welcome. Please keep the palette bright and vibrant throughout, with careful attention to balance so the colours energise rather than overwhelm. If you have questions about exact hues, texture treatments, or composition ideas, feel free to share mock-ups before finalising. I’ll give timely feedback so we land on a design that truly pops on the wall.
