Very cool art, I wonder where it came from? Is there no way of finding out?
Anyway, the Begins suit is perfect for me and requires no further enhancements - the cowl is explained, the way Bruce acquires the suit and the Bat-gadgets is perfectly logical, and even the arm gauntlets used are taken from his days when he trained with Ra's al Ghul.
I never liked the idea of Batman changing his suit every five minutes either, or him having a wardrobe full of spare suits, for example as seen in Batman Returns.
It makes the image of Batman seem more powerful if he has only the one suit.
