Seems neat, but the base bricks aren't well hidden enough making the entire space seem boxy.
Mainly on the edges of the water and boundaries. Try exploring a bit more with built up terrain.
Also, the detail placement seems a bit overkill. You can get a nice effect without overuseage in-turn cutting the brick count.
Not bad all in all, many wouldn't even take the effort to try doing this.
7/10Edit: Eh, he never said we could rate this..
