These are so very cool looking.
I have 3 set ideas for you.
1. The Zulus with there kite cloth shields
2. The Gualic Celts that fought the Romans in France and Germany. (Particularly the Mad-woman battle druids would be interesting as well)
3. My last set is animal battlers that fits the same size and style as these battlers. (and things like the Elephant riders)
Thank you. I really like the idea of Zulus and will add these, but Celts will have to go to a maybe section, I think I have couple on the list that would look very similar to those. However if I'll ever have more time, I'll be sure to add them.
As for the animal battlers, these will go into a different thread at some point, there will be more mythical creatures and such, I'm not sure if I won't make a resource pack with those, you'll never know.
There are some underwater battlers I did a while ago if you would like to look at that, but they do look more like pokemons rather than animals.

Once again Thank you and I'm always glad to get some feedback and good ideas.
I rarely post on something but I had to say;
This are good, and I mean, REALLY good.
Keep up the good work, you have an awesome talent for this.
Bah, Your too sweet! Just feeding me compliments and making me, all chubby and plum. Just, stop it! Your making me blush! Thank you!
So are you open for hire?
Well, I'm not exactly open per say, but I am willing to work only on smaller projects, nothing to big that would take full time out of my day, if you know what I mean

I hope that answers your question.
