For me, looking at this map is confusing. Either go all out with the funny cartoon look or go out on the graphics.
You have a realistic looking gold at the top and boats but your gold diggers are "cartoony". Try sticking to one theme (like doodle earth, I don't play that map often but love how the map maker stuck to one basic theme of crayon childish fun). Also it seems like a lot of wasted space on the map. Is there a better way to bring it all together so it doesn't look like random images being thrown on?
