I'd like to share few tips as well, if you don't mind
-Some roads are not connected and they look odd/ cut off.You might want to remove some of them.
-I see you used terrain flat tool, but haven't smooth the area. For roads you might try smooth or flatten road tool (it is an icon next to road construction tool).
-Painting terrain is always tricky. To keep areas from having too sharp terrain edges, try lowering paintbrush falloff to the 10/100 and opacity to the 25/100. Play with that to see what will give you the best effect so transition from grass to sand is looking more natural.
-Those 3 striped buildings are not looking good, I believe they are CC, but regardless they are not looking as detailed and neat as others.
I love the pictures you added. Keep taking pics in Edit in Town, they are much much better looking then those from raw CAW.
