The landscape is quite good. However, there seems to be an issue with the victory condition. At least, I didn't see anywhere that it mentions anything about killing a neutral hero (text doesn't count). So, it seems that destroying the red player is enough for victory (and there, the standard victory condition is also allowed, so it's already quite simple to just defeat the red player).

I liked the map, the landscape is well done.
