The fontwork is a cliché. I can say that its the most commonly used
font here and does not really make a design stand apart. Refer to
previous FUDCon T-shirt designs. I think we should follow the
tradition - city skyline vector/identifying figure -> vector rays
->city name -> we are done :) (Or something radical is welcome too)
Though they are all almost same, but Thats the only one I like.
I'll try to do some mockups too if I get time today.
