I think you have a lot of unfinished business, especially concerning descriptions and icons. There are a lot of spells you haven't wrote a description for, mostly there is no description when you learn the spell. You haven't added the Disabled icon for all the imported icons, meaning they just show green squares.

read the part about importing icons
Also the heal spell for one of your heroes is bugged, when you use it once he keeps using it until you make him do something else, I don't understand why you based this of the heal spell instead of the holy light spell.
The icons for the spells are nice, but else then that, there's nothing custom about the spells, even the values and effects look exactly the same, it's not so hard to change this in the object editor
Terrain could use some improvement, more doodads mainly, and some more tile variation
Also didn't you have the destroy the 2 buildings at the start? They were invulnerable, or did u just have to kill the 2 bosses infront of them?
Except from that, the map was decent, you have a base, all you need to do is improve it
