I just wanted to say that I really appreciate the single-civilisations library besides Civ Gold. Please keep it up. I am one of those who only seek their favourite Civ without downloading all the masses that exist.
In the near future, all the individual civs from Gold will be modular - i.e. able to loaded separately.

shows that it is possible. Rather I like still images like in Wyz First peoples mod than clowns like the Civ 4 Sioux-Leaderhead for Sitting Bull
CIV3 is different, though. It was much easier to create custom leaderheads in 3 than in 4. The file types are considerably different, and what is possible in 3.0 cannot be easily done in 4.0. With all due respect, I still find that most new leaderheads in 3 all look alike - only a few base models with lots of modifications.
I went with pic leaderheads for some of my mods - First Peoples, Out of Africa, etc. - but the community consensus seemed to be that static pics detracted from the flow of the game, hence the use of reskinned 4.0 leaderheads.
Certainly the intent was not to make them look like "clowns". All respect was given when creating those, just as when creating any LH.
Unfortunately, BTS only provides one Native American model to work with, and Gold will have 10 first peoples civs (obviously you can only do so much with one LH). So you will probably not like the fact that some of the Gold models will not change. (4.0 adds a lot of native empires, so the leaders may not look as you hope)
However, if you have any suggestions to provide - better base model recommendations, recommendations on accessories/colours, etc. Please visit the Gold forum and post them in the North America section and I will gladly look at them.
