Isaura thumbnail Ideas/ rough map layout

theses are just short thumbnails of how I would possibly construct the final 3 concepts 

           with the different dark shades of colors giving a ominous vibe to the city of wells, the 3rd                     picture  show a temple for religious worshipers for the city

the final picture just basically shows a rough Idea on how I would like the city of Isaura to be constructed and to give me a rough Idea on what i need to do for the different shots for each piece of concept art.
