I've just release some lhs I was working on, see
http://forums.civfanatics.com/showthread.php?t=330562. There's an ultraviolent version of Attila (so called Attila at work edition) as well as the revised Attila and Ruga.
As for the third hunnic leaderhead (whoever that will be), I am currently thinking about the ancestor LH that someone made to be used as a base for other lhs. The Capos Hiawatha (see his lh thread for preview) seems to be based on that as well. I already distorted the skull so that it resembles the huns heads. Also, I would give the guy Koppánys beard (see my lh thread that I have linked before) and maybe one of Ghengis earrings. At the moment, I think I would keep the guy a skinhead, but I xould adopt The Capos HIawathas hair part and make it a bit more descent. I wouldn't give him any other hair nor a hat. Not sure about the body. One could leave it naked and only add some fur parts and / or make the body more hairy and sweaty. For a leaderhead like that, I would need help with the texture in any case.
EDIT: Regarding hunnic kings, this is what I could find through a quick search:
1. Balamir / Balamber - the earliest hun leader I could find, that means if we do not take the Xiong-nu in consideration, which we should not IMO; he's said to be a personification, not a historic person
2. Baltazár - son of Balamir; burried in Kiev
3. Uldin - son of Baltazár, did not rule over all Hunnic tribes
4. Charaton - said to be the first king
5. Octar / Optar / Uptarus - brother of Mundzuk and Ruga; all three seem to have participated in the unification of the Huns und could therefor get the same traits as Ruga making the two brothers needless
6. Mundzuk / Bendegúz - seems there is no proof that he was king, but things seem to support that point of view
7. Bleda
8. Ellac - son of Attila
9. Dengizich - another son of Attila
10. Ernak - another son of Attila
11. Basich - seems like few is known about him
Seems like a divided ruleship between brothers was somewhat common amongst Huns, which reminds me of the kende-gyula system of the early Magyars. In this case, Bleda would probably have different task areas then Attila, although certain discussions might have been done by both. Anyways, it seems to me like Rugas generation is already represented as from the sources we have, no other traits then Rugas can be determined. Not to mention the earlier kings and rulers of whom we almost only know the names. Attilas sons don't seem to have been successful at all. Anyways, agressive or expansive could be given to all of them... Well, if you guys can come up with suggestions about traits or further leaders, feel free to share them. From my part, I start liking the idea for the leaderhead I told you about, more and more. Yet I'd need help with the texture, that's for sure.
