As I see you adding to the tileset, you are doing what we "were" doing with with Kailis' tileset for the world map. However, since then I've decided to break them up into smaller pieces. But yours may work out a bit better since it will be more of an ever-changing cityscape. Will finally be nice to see a real modern-esc city for Breeze, I'd definitely say adjusting that one tower you had made, to fit with this city, you could really make a beautiful city tileset with a few skyscrapers!
