Modern Portrait Poster Design

I’d like a striking, gallery-ready poster built in Photoshop that turns a single portrait into a modern art piece. The goal is pure visual impact for display, not advertising or event promotion, so feel free to explore bold colour work, clean geometry, or subtle texturing—whatever best captures a contemporary feel while keeping the person front and centre.

Please work at 300 DPI on an A0 layout and keep layers organised so I can tweak text or background elements later. Deliver the final print-ready PDF along with the layered PSD. If you use any premium fonts or stock elements, note them clearly so I can license them if needed.
