The first map is boring and full of bugs.
First of all, your cinematics are not good at all; the fade out/in effects are not set up well, the camera doesn't reset itself after the cinematics are over and it moves very slow in some of them.
Not to mention the content of the cinematics, which is boring and lame.
One more thing; you can't cancel the cinematics in case you don't want to watch. it is very important to make this option because there are people who doesn't get interested in things like that and just want to play the game (In your case the cinematics are just bad and embarrassing to watch.).
As for the quests: they are pathetic.
The main mission: to prepare for the battle against the Dark Iron Dwarfs is very easy.
First, you give the player so many units in the beginning so you can survive the attack without building a single unit.
Second, the triggers of the quest are messed up; the enemy units are moving to the beginning of the ramp, but don't proceed towards the gates. You can just pull all your troops back into the city and wait until you get the message: "You won the battle" because they don't try to attack you.
After you win the battle there is another quest but I grew bored and exit the game at that point.
Another thing I have noticed: your concept (at least of the first chapter) reminds me the first chapter of "Dwarf Campaign", only bad. Your quests' concepts are very alike, only that in "Dwarf Campaign" everything is balanced and ticking right and in yours everything is messed up and failing.
I suggest you take a look at the GUI of Dwarf Campaign and see how it's done; maybe you will learn something.
About the models; the models are overall fine (except Rend's model which is terrible). But the portraits of some of the models are not functioning or exist.
About abilities: you didn't bother to create any new abilities, which is very disappointing.
You must fix the food issue as well: there are too many units. It is impossible to build so many burrows in such little space.
About items: too many books, which are causing the hero to be overpowered.
Overall; the map needs a lot of work and I can't give you my honest opinion until you will deal with the major problems. I can't also continue to play because the game is not fun and I don't except it to improve if you can't even make the first minutes of the game right.
