- Match the t-shirt color in the mockup exactly to the color used in the original design.
- the design targets Female, feature a realistic female Fair skin and American model wearing the shirt, performing an action that fits the theme (e.g., cheering, celebrating); vary the pose each time rather than repeating one pose.
- Keep the same overall theme as the original, but make the design itself different — not a copy. Use the exact original wording only; do not add any extra text.
- Keep text, numbers, and any character/cartoon elements separate and non-overlapping (never merge a character onto a digit) so the design remains fully editable. If an age or number appears, leave clear blank space beside it for future edits.
- Build a background that matches the design's subject and looks authentic, never generic or fake. For sports themes shown without the actual object (e.g., a football design using a flag instead of a ball), use a realistic, relevant stadium setting.
- Exclude any real or official brand, team, or league logos.
- Deliver the final mockup as a square image, 1:1 aspect ratio, high resolution.
