Crash

Yes, the design is good (I can even say that). For first works, it's very, very decent. There are a couple of points that would be good to fix (or keep in mind for the future): water should be made the color of water by setting ReflectiveWater=true in the map settings; empty areas are better filled with objects, and roads should be made non-rectangular; also, you can "deeply" submerge the elf castle using simple River water. And I recommend trying to move from flat design to volumetric design for subsequent maps
