All of the models don't have a proper or attractive birth animation. If I was a moderator I'd tell you to go fix 'em. Also, if there aren't attachment points and collision shapes, consider installing them on.
EDIT:
I tried to open Abyss Rift with War3 Model Editor v1.07, but - "Expected a VRTX tag, got a '*' tag"
So, your models are also broken. Nice.
