I looked at the screenshots. The descriptions are poorly written in terms of spelling. If you dig deeper, the narrative itself isn't great either. I would also rework the names, as calling creatures "Gnome Gods" sounds absurd, not to mention "Silanas" (Silana is a goddess herself).
Magic birds are listed as level 7 creatures (visible in the screenshots). In terms of diversity, all level 8 creatures somehow look the same in terms of abilities. I saw only one level 7 ranged unit (although cyclops could also throw goblins). I have no complaints about the visuals; I couldn't do better myself.
The mod's idea is interesting; overall, if you refine what's there and add another five level 8 neutral creatures, it will be really cool.
