One word of advice for AdultRMX, he probably figured it out already, but just in case - its wiser if he extends the design from the front of the box on the left and right side like its a continuous design. For mass production, you must always keep in mind that when they punch the box, after printing, the die can slide about 1 mm (sometimes even more) to the left or to the right. Its easy to extend the blue shapes and it doesn't affect the main design much.
Great contest and excellent entries, keep it up guys!
