After a while trying to mod gender for Creatures, it seems that features is tied to humans only. It would be cool if we could use it on custom creatures to allow variation in them like Husks having different heads choices and body types with the gender and race values.

Another thing that would also come in handy would be to allow more than one creature type to spawn as a group. Like Human Husks and Crawler Husks, for instance.

That would be neat, most creatures in earths oceans have a female that is bigger than a male. Also if you go in different areas that are far apart from each other diff rent species/breeds of an animal could be there. Ex: In the southern part of the map smaller creatures but faster speed or different colors, slightly bigger fangs, etc...
