Sounds pretty cool - If your looking for new ideas for terrain/dungeons you might want to check this
campaign out - chapters 5 and 6 deal w/ pirates and the cliffs are re-skinned to make a pretty convincing harbor/pirate ship environment
Edit - OK, tested it out. That was pretty sweet, well done so far. Game-play was very nice, though as many people said first aid was overpowered. Diablo movement system in that would kick so much ass

You should use the portrait file for your hero though, seemed like your model edits also used a portrait animation to the model. Watcher model is nice, but the face gets these awful shading lines around it in the full-scale model, while they are nonexistent in the portrait file. For the hero you should defiantly have a portrait model to go with it, at least if you don't plan on re-working the face. Anything else it doesn't matter.
As for the terrain it could use a little more love, one thing I found out looked pretty cool for terrain that has no mid-level use is to skin the cliffs like this -

change the top to solid black an have the tileset it connects to to have a black tile as well, making the areas you cannot reach an empty void rather than a fogged-out roof

. Works for me anyways, I think it gives a nicer look to dungeons, and their is no question that you cannot go in the empty space (not that their really was for yours).
Unfortunately the dungeon tile connecting to the man-made cliffs only has two variations

- but if you import custom cliff skins you can use any tileset you want
Hotkeys were not to hard to get used to, though a W A S D system would probably be a little friendlier, though I have seen some systems that use
Q W E R
A S D F
Z X C V
for abilities in WC3 based on their location in the unit interface.
Creeps could probably stand to hit a little harder, though it seemed kind of like rampaging through the Blood Moor - which isn't a bad thing if it's the first level/intro. The camera system and switch between different areas was very nice and well done.
Cool map/campaign so far, can't wait until you complete this
