btw, would it be too much if you move the logo a little bit to the right (it's left if you're wearing the shirt) with the words sa other side? para naka-tapat ung logo sa heart. though the heart is actually located at the center of the chest, symbolically sa left sya dahil that's the direction it pumps blood. the heartbeat is louder sa left side of the chest if you have noticed.
as for the quote, align right na lang ung words to maintain the balance.
then same thing goes with the rays as we have previously described.
back design details: we take off the background of the logo. therefore, mawawalan sya ng shape dahil aalisin ung shield border. what remains is the white cross, the green cross, the heart with 7 swords and the eagle. but the white cross will simply be the shirt itself. so it's like we leave a part of the shirt unprinted in the shape of a cross and it extends from the neckline to the bottom of the shirt.
the green cross, heart w/ swords and eagle will remain as they are then the background will be the rays (coming from the front) converging. so it's like a big logo sa likod without the shield shape. para hindi sya masyadong redundant since meron ka ng logo sa harap. we will also omit the 'JUVENTUS' sa likod syempre.
just a thought. I hope na-gets nyo hehe..
