The pictures below show my first attempt at painting flats. I ordered a unit from Berliner Zinnfiguren, and painted them up in a rather simplistic style with a minimum of layering. The regiment shown is the (Seven Years War) Prussian 1st Musketeer Regiment Von Winterfeldt. I used the same decor as the halfling pictures below - it saved me some time of getting out my proper 18th century buildings ;-)
Although they look not as nice as the multi-layered flats one can find online (and which are real pieces of art), I prefer this toy-soldier style for gaming purposes much better.
