Le Monkey face is what making superman so good, though if civ6 turns out finally more realistic than current "the trolls and gnoms" style I can just edit face.
Those are Stephen Bathory and default Khmer leader #1.
I have used Sculptris and Photoshop, Bathory was my first 3d stuff ever made. Hella proud that I finally give 3d a try. I decided that civ6 style allows low quality 3d stuff and I think it turned out ok. I mean it turned out amazing, I think I have already reached 60-80% of quality and what is more important It would allow me to keep one style for all leaders, something which I lack in civ5. In Khmer model I have even started modding details, like chain or crown (well, Khmer crowns are extremely detailed, mine is the best I could do).
You know, right now I hope that Firaxis will flood civ6 with civ/leaders dlc and there will be no need for low quality mods. In general it is very bad moment for new civ mods, in civ 5 I started modding a months before BNW with clear situation. Anyway I am waiting for first expansion right now, which may save this cheap copy-paste called civ VI.

Trying to stay open-minded and positive.
I am enjoying 3D modelling and probably gonna make some more leaders, though the obvious problem is what to do? I wanted to go with Sitting Bull next, but there is so high chance for Firaxis to do him. Crazy Horse? Knowing my luck Firaxis would made him instead Sitting Bull. In case of Bathory, I am relatively safe (but who knows), from what I remember Khmer has at least 3 viable leaders so I am safe here.
I wanted to do Prithvi Narayan, but he is also in danger zone. Yaa, that is why it is not good moment for new civ planning.
It is hard to find an interesting leader, that would be interesting in artistic way also, that is safe from being in the base game.
I decided that 3rd model is gonna be Henry Morgan, I hope he is relatively safe as well. I think the hat and outfit will make him artistically interesting. Maybe a hand with pistol shooting to the sky?

Or pointing toward player.
