Uhm, where do I have to start..
-There are too much places you could fill in with houses, caves, etc.
-5 photo's aren't enough photo's to decide if the map is good enough or not.
-The trees you made are on 1 place. Maybe you could spread them a bit?
-This doesn't give me the ''Colosseum'' feeling.
-This is called Colosseum. I had expected a middle ages build style like medieval or something else, but the builds are fine.
-I like it how it changes from oak wood ''biome'' into a spruce 1.
-The map is way too big.
I like the map theme, but this isn't good enough for me to get added to cubecraftgames' survival games.
Maybe a revamp from the Builders of cubecraft?
Anyways Good luck!
