3x5ft Detailed Artwork

I have a single reference image that I’d like reproduced as a high-resolution artwork at a final size of 36" × 60". The goal is to match every detail, colour tone and texture( including the fabric texture) exactly as they appear—no stylistic changes, no added elements—so the finished piece looks like a faithful, print-ready enlargement of the original.

Scope
• Work directly from the attached image, copying its existing style without exaggeration or abstraction.
• Maintain sharpness and texture clarity at true print resolution (minimum 300 DPI at full size).
• Deliver a flattened, print-ready TIFF, plus the layered source file (PSD) so I can make minor tweaks if needed.

Acceptance
Once the file is printed at 3 × 5 ft and viewed up close, all original details should remain crisp with no pixelation, artefacts or unintended colour shifts.

Let me know your preferred software and estimated turnaround, and feel free to flag any technical constraints before starting.
