Abstract Geometric T-Shirt Graphic

I need a high-resolution Photoshop design for the front of a T-shirt. The artwork must be purely graphic and follow an abstract, geometric theme—clean lines, sharp angles, layered shapes, and a sense of depth that will stand out whether printed on light or dark fabric. I’m flexible on the colour palette, so feel free to suggest what will make the composition pop while still printing crisply at 300 DPI.

Deliverables
• Layered PSD (minimum 4500 × 5400 px, 300 DPI)
• Transparent PNG ready for print
• Quick mock-up on a blank shirt to preview placement

Keep all elements vector-shaped or smart-object based where possible so I can scale or tweak colours later. Let me know your vision and any questions you have about style, layout, or print constraints so we can get this ready for production smoothly.
