Love the elvish nightime =),
but as i see i am little questioning the strategic purpose of elvish town. Since Humans have river/many layers and that stuff, than orcs have bigbig city that masses of hords defend it so it doesnt need some kind other protection, than there is elvish which looks similar to orcish one (wall is rounded and it is waving and have 2 layers) but they dont have masses to make up for that (aka same vulnerable from all sides so everywhere needs to be guarded on same lvl).
Or am i missing something ?=P
Well in my logic, since they are elves and that live with nature, they would help themselves with some natural defenses.
