I'm going to be brutally honest here, it looks like someone took a shit on the World Editor. It's just random stuff thrown together.
The plants and trees don't even match, you used fall trees with summer looking plants and nice green grass. You used the worst tileset known to mankind, and didn't use any tile variation.
Blizzard cliffs are ugly to start with, and you managed to take that to a whole new level. They look awful. I think you thought the statue and footman were cool looking so dropped them in there too.
I have no idea what that huge black spire is, but it's ugly. You made this at the edge of the map and therefore anything behind your waterfall is going to be black. Your terrain ends after the waterfall. You always should give the illusion that the terrain goes on. Use fog and mountains to do this. You don't seem to know where the smooth tool is, or don't know how to use it. Everything has really sharp edges and looks so unnatural. You just spammed doodads all around the waterfall, but managed to miss the whole front area!
I guess one good thing is you weren't afraid to use doodads. And the waterall itself isn't too bad.
Well you said any opinion. This is probably the worst critique I've ever dished out. Not sure why I took it out on you, because this isn't the worst I've seen.
