While I agree that Panama and Cartagena should be commerce-rich cities, I'm not so sure about removing the Pearls from Venezuela, given that this was the first resource exploited during the colonial era. Nonetheless, I'm not against adding another Pearls in the proposed location. About the change in the Gems, they represent Emeralds (if I'm not wrong, merijn even made a green Gems version so that we could add it) and I'm not against moving their location to open space to Medellín, even though Bogotá would probably be founded 1SE from that title in most games. When we were discussing Colombia, one of the main challenges was making room for her canonical cities whitout enlarging the continent (we could use another row of land near Equator to improve South America's shape, however Leoreth was against making any large changes on map). About the lagoon, as I see it is already included and the water title represents the Gulf of Venezuela. The exact location of Maracaibo would be in the border between these titles.
