How about for every Painting you paint! It'll be like MKDS paint but putting it on Sheilds, Weapons, etc! Just a thought of and a idea to represent your name better!
it should have a sepreate paint section in the TMJ area that says "Design Armor,weapons etc"And when you make some you go to some thing and you choose which character then you choose what to put on it
Based on what I've seen from the demos, paintings used for armor won't happen. But I'd be pleasantly surprised if user avatars would be somehow visible in-game.
