Let me review this one for you.
First of all the terrain is symmetric and the layout isn't that bad at all but your terrain designing is so lacking.. the smooth terrain tiles is nice but I mostly recommend the default settings of tiles to newbies, wanna know why? Because the smooth tiles looks fucking ugly if the overall terrain is empty. You should add more environmental stuff like flowers, rocks(this one can do some magic), fences, lanterns, logs etc. Using the cliff inside the map and not just a decor shit outside the playable area is highly recommendable to melee mappers as cliffs does look good if used well. Also painting some big parts of the map with nothing but Ashenvale's dirt and rough dirt.. then your map is in a big problem they just doesn't looks beautiful at all so my tip to you is to use most of the tiles randomly as they look better that way than painting one or two tiles on big parts.
About the gameplay. Well there is nothing really special about it. Just a expansion mines, wells and a tavern. Try to add a goblin shop or a mercenary camp. Overall its a nice small melee map that can be approve. 2/5.
