Very interesting graphic. I can imagine how cool the stitching would look but I think maybe you should have converted your line to dashes so everyone got the idea right away. Anyway, a solid 4 for concept and art.
Maybe add some color shirt options next time. White stains easily, yellows instead of fades and it makes people look bigger. A lot of scorers have expressed their hate of it. This would look great as a white graphic on dark gray, red, or gold for instance.
