I may experiment with other setups, perhaps with visible feet as well, and maybe some interior backdrops. At the moment I used a couple of pre-rendered from a martian surface object to save time on image rendering when they are fully rendered.
I will also be making some exra props, such as a radio or helmet mounted lights to pick out indivdual details. They will probably have more detailed hands and feet, and a custom chestplate with a flag or icon to show thier identity (at the moment it is made from two sides with a symetrical texture that meets in the middle to save render time when they are units, but won't be such a reduction when doing leaderheads). I may also experiment with illuminating thier faces a little, but this will mean producing more customised heads, which isn't such a bad idea especialy if some of them are going to be indoors and will carry their helmet under thier arms.
I'm hoping there is going to be someone who doesn't mind making some flicks from the raw renders for us, because I can only produce standard flic files with openFX, I can't edit the pallette.
EDIT; the other cool thing about this idea is that you can have a lot of expression that is not available in normal leaderheads. For instance say you have a the transnational corporate civ, Subarashii which is a very militant, traditionalist japanese organisation. You could realy add some character with either adding feudal japanese touches to the space suit, or have the leader dressed for indoors, with a kimono and samurai sword, with a large window showing the martian surface in the background. In the happy pose he could bow a bit, while in the angry pose he could start to draw his sword...
