Manual T-Shirt Model Mockups

I already have several clean upper-body photos of my model and up to five different T-shirt graphics, but the graphics are only available in low-resolution files. I want each design to appear naturally on the model—correct perspective, realistic folds, shadows, and fabric texture—using traditional editing techniques such as Adobe Photoshop smart objects, warping, masking, and manual shading. No AI or automated mockup generators, please; I need the handcrafted look that comes from a skilled retoucher.

What I will send you:
• 3–4 high-quality JPEGs of the model (upper body)
• Up to five PNG/JPEG design files in their current low resolution

What I expect back:
• One finished mockup image for every design (total of 1–5), delivered in high-resolution JPEG/PNG suitable for web and print
• The layered PSDs so I can swap colours or tweak placement later
• Consistent lighting, colour matching, and a seamless blend between artwork and fabric

If the source artwork needs a quick clean-up or slight upscaling to hold detail, please factor that in. Turnaround within a few days is ideal, but let me know if you need more time so quality doesn’t suffer. Looking forward to seeing the shirts come to life on my model.
