Looks wonderful, but a little bland, I understand the desire to stay true, but you can and give it a bit more color. Also, you should consider figuring out a way to make the map playable, I know that isnt what you made it for, but it would be fun!
It looks good, but could use a little more map detail. I understand the map is not for playing, and this was made solely to get used to the new Forge controls.
