I found these a bit annoying and fiddly to paint, though I think they came out looking ok in the end. I'd say they actually have too much detail and some of it obscures things that you'd like to paint - for instance, the cartridge case makes it about impossible to paint the turnbacks. I ended up spending a bit longer on these than I should have done, which was mostly my fault for not going about them in a logical way.
Face, trousers, gloves, jacket, epaulettes and carbine are all done with colours as per the infantry a few posts down.
The yellow cloth is GW Golden Yellow over GW Iyanden Darksun (one of their foundation paints). This doesn't give great contrast, but the foundation paint goes on nicely over a dark undercoat in one coat, and the yellow brightens it up a little.
Plumes and horsetails are just VJ London Grey drybrushed over the undercoat. The sheepskins are white dry brushed over USA Tan Earth.
The black horses are a mix of Iraqi Sand and Black heavily drybrushed over the undercoat, then given a black ink wash. They look ok up close but at any distance its hard to tell they're not just plain black. Next time I'll try something with a bit more contrast.
