Hey... Umm... I don't know if I'm suppose to post anything here or not, but I thought I should point something out to you.
On the castle itself, I guess that's suppose to be a private patio or something for the king to walk out on? But, that is actually kind of the wrong tile type to use to me. It had me thinking that there was a suddenly large whole in the castle leading to the rgounds below. You might want to think about changing the color to something less... greyish I guess...? Just a friendly openion mind you. :)
Other then that, amazing job! I just don't see where you people get your skills at... I have done city after city in my games, and in the end, I end up tossing them, seeing as how I just can't get the cities down right and they end up looking horrible. :) Beautiful work folks! :)
