Uh, making screenshots by night is not a very good way to showcase your map.
What's wrong about taking screenshots in the editor (just curious)?
good that you've added extra detail in your post here, about spawns and walk times..but the dark screenshots kinda pointless
There are some graphical errors with shadows and water while in the editor,
so it makes the map look a little derpy sometimes.
Also, you can't see the flag while in the editor.
updated screenshots help....sort of a castle in the swamp being renovated? :)
aesthetically, i would paint some other ground textures here and there for variance, like maybe sand along the shore lines a bit here and there, some earth somewhere, maybe a path texture or village texture in places where people would walk....etc.
maybe a bush or two? some rocks?
maybe its that green color....its like 70's green :(
might be better off to go with the various textures rather than the color painting...those have built in variance for a more real look.
up to you!
