i quite like the city symbols.

i think with regards to the water/coast/wave lines, 3 might be better. and id remove one of the ones closest to the land as they seem very tightly-packed there. other than that i quite like this, including the distressed pape, though id keep it hiddenn while working on it as its quite distracting. then you can mess around with layer styles & opacities and what not once its done to see what you can do
