What did you use for the emblem Champion? Did you paint it on using fabric paints, or did you do silk screening? Silk Screening (Now used with polyester but the name stays the same) renders very crisp emblems and graphics on to pretty much whatever you need it for that is a relatively flat surface. it also allows for you to do incredible detail without having the hand needed to do it with fabric paints.
But you would have known that already if you used a silk screen for the shirt.
