This Metal Chick tee was a product sample just to see how the print quality at Zazzle has changed over the years. It hasn't. This design was chosen because well, it was better than most of the stuff on Zazzle.
As for the design itself, it isn't professional by any means but it isn't the worse design of all time. Perhaps it's the worst one reviewed here. That is mainly a reflection of the lettering that spells out "Metal Chick". The designer places it on the girl's head. Why would anyone do that? Placing it all the way above or below the image would had been better. The lettering has highlights on the top and bottom, which kills any attempt at a 3D effect. The actual drawing of the 80's metal girl isn't too bad considering it is done by an amateur who is just dipping their toes into the POD industry to try to make a few buck. But it is the level of artwork to expect at Zazzle, Cafepress ( To Hell with Cafepress BTW), Comboutique etc.
