No problem in creating a different set of icons for each age -or even for each "cultural sphere" -but that's beyond me. I wanted precisely the universally simple and recognizable *timeless* icons of Civ1.
Morten,
I agree with you about not creating the icons for different ages. I just released a modpack similar to yours (similar in that it changes the people faces... but very different...

)
Anyway, to solve your nationality problem, I have a suggestion (if you're interested enough to do it).
Download my modpack Smiley People (you'll find a link in my signature)
Load both images in whatever program you're using (I assume Photoshop).
look at the necks of my *people*, you should notice they're colored in 3 shades of green. Those are 3 of the 6-7 (I figured there are that many but didn't need all of them) colors that CivIII will automatically colorshift to identify nationality.
If you use those same color locations (by color locations I mean location in the palette map) you can paint some features on each of your people (for instance the farmer guy could have his blue outfit made green, the girls same etc. etc. maybe the unhappy guy with the flag you could do just the flag...) This will give you 3 shades that are plenty for the sizes we're talking about.
Your modpack uses a slightly different Palette than mine (mine uses the exact same palette that came with the original CivIII people heads file) so you should change the mapping in your color map to have the 3 greens identical to mine. The reason for this is that if you don't, then you'll probably find that what looked ok in green won't look as good in red, orange etc.
Shouldn't be too big a deal and you may find you like being able to know nationality of folks... after all we're talking slight change to a palette and adding a dab of color to 11 pictures.
Let me know if this helps in any way.
