The map is very interesting, and I'm enjoying playing it. I see one problem: the difficulty curve. For a casual player (like me), the beginning is very difficult, even on Warrior difficulty (I didn't bother and am playing on Recruit). But after that, everything is fine, and you can even use the autobattle feature. A hardcore player, on the other hand, will undoubtedly be pleased with the beginning, but the rest of the game will likely disappoint them. I think that to combine the interests of players, the number of neutral creatures should be made strongly dependent on the difficulty level. First of all, this applies to the bridge on the road to the first castle and the garrison of that castle.
And one more thing. Since the portal to the castle has been removed, maybe it would be worth adding boots of speed somewhere? At least, to the gates of Gardholm. It's annoying to have to run back and forth for a week...
