Grass colour is MUCH better (I love it now!) but it is still unclear that your castle is on a hill. You need to work on the lighting/shading to make that hill a hill. I preferred the grass/hill on the second last post because it was brighter.

I agree with you in terms of layout/tidiness and am having the same problem with 'Big Castle' ; however I really like your internal layout of map 2.

Also, are you making one castle to use on all four of five of your forts on the worldmap, or will you be making each individually? If the latter case, each could have an individual layout, and you have four or five ideas in this thread already.
