Such an awseome city. In fact it is so cool it doesn't even have a name. The city comes complete with streets. An underground train. And a monorail. You say you want more. Then go to another city. Map made by my brother Joker Guaranteed and myself.
I really like the concept of this map however it could definitely use some more aesthetic touches. You also seem to have a lot of straight/large areas of track which isn't necessarily bad but you might want to switch it up a bit. The underground train is a cool idea and hopefully you will work on a version 2. One last thing, try to include an overview pic of your map because it is hard to get an idea of the whole thing from your pics.
