Very simple map. Works well. I have dreamed about really nice Elven fortress but this is not the best one. Still nice for first map. If you have time, please make a bit bigger map like 2v5 and add some details to the fortress. Maybe it could be in the side of the mountain or waterfall like Rivendell.
I gave you a 3.5 on playability because the walls are pretty well done and there is enough space for farms; but the map itself sucks, sorry. There are no mountains, it's mono-textured, those bases are not needed and look ugly. Also it's just a plain wall, there's not much of creativity on that fortress. I suggest you to open other high-rated maps and see how people do it. Still not very bad for your first map, the object placing for the wall makes me hope you can do better than this.
