i will not review complete this one, prefer to leave it to someone more experienced
a little of feedback, the terrain and the enviroment, i dont see it.
I mean you mixed the Lordaeron tile set with a dungeon theme
it will be really better with the Dalaran, Ruins of Dalaran, Underground, Black citadel and Dungeon tile set.
and i tell you why
in the sets i already metioned, flat terrain is not bad, but here in the lordaeron set is not good.
The idea is good, but i think the basic concept between a wild terrain and a dungeon is confused in this map and the mix dont work, if you use wild terrain in the external part of a dungeon is okay, but here is a really bad mix.
edit(the Lordaeron cliff as wall, mixed with forest and jungles inside and the white marmol in the floor it look really unnatural)
Im telling this not to be bad, im doing to improve yours skills.
and the problem here is the bad mix between a dungeon and a wild terrain.
if this map were mine, i will do it again with a proper dungeon tile set and only use wild terrain in the exterior of the dungeon
a bad enviroment can kill an entire map... im sorry,
with all respect, im not voting for approval.
