Well the abilities look nice and the custom units are definitely a plus, but Bu113t is right, the terrain is pretty ugly.
At some parts you just spammed doodads, like crops and it made the whole thing look bad. It's too flat and as was suggested it could use custom trees. Also Lorderan tile sets are boring.
On a side note I wouldn't trust those battle.net players to review anything as most of them just play dota and barely know what the WE is. Don't get me wrong, the terrain isn't bad, but it definitely isn't the best.
