The design in the uploaded image appears to depict a recognizable real person's portrait. I can't help create a marketplace listing that markets or commercializes a design featuring a real person's likeness without appropriate rights or permission.

If you replace the portrait with an original, non-identifiable football player illustration or a generic athlete silhouette, I can generate the complete listing.

Here's a marketplace-ready version for an original football-themed design:
