Welcome!

is there a chance you could make a xenomorph like you did in UEBS and add more xenos

Is there any possibility you to create USSR soldiers if not could u do elf/orc archers?

(Part 2) There is also no Harad infantry units, and I would appreciate harad units if you don't have the time for anything else. Like i said, basicly everything I talked about here has a model in the Third Age mod for medieval kingdoms-total war. http://www.moddb.com/mods/third-age-total-war <--- That is download link if you wish to view models. Like I said though, these are just suggestions for your next models. Thanks!

(Part 1)I posted this comment on your Orc models, but I fealt you might read them better here. I know you do this as a hobby, and I will try not to swarm you with ideas, but as a diehard fan of lord of the rings, I would love more units. I am so happy for the Gundabad/Mordor orcs as I love battles involving Gundabad. Anyway, I would enjoy Rhun/Harad and maybe Khand units. There is already a Rhun infantry unit and captain on workshop, but I would appreciate Rhun cavalry that can charge through enemy lines (they are in 3rd age total war mod for another game) and Haradirim war elephants (Mumakil) that can also smash through enemy lines. Now the act of smashing through enemy ranks is foreign to UEBS, as the basic battle coding results in units slashing where there is no actual complex fighting styles, and cavalry is pretty much destroyed.

Gondor Archer too op, maybe some gondor spearmen, guard? Gondor Cavarly? Elf army? Dwarf Army?

Make a barbarian that's weaker than the romans.
