What a neat idea! I almost wish the robot was on the front just because it's the best part of your design, but the robot arms across the front can catch someone's attention and make them wonder what's on the back. One more thing - make sure the robot's arms don't print over the hem line/shoulder of the shirt. It might violate the contest guidelines. Just something to consider. Very cool entry, good luck! Please see mine at [link] , and thank you!
