I put the flags down as a quick test to see how the facing colours and flags looked together. The only one I'm not sure about is the Austrian flag in the centre. Apparently it was used by some regiments in Austrian service. I thought it was a good idea at the time, but now I'm not so sure. I think I might replace it with one of the white flags at the bottom of the picture.
A closer view.
Another closer view. This view compares the units at the back which have been given the liquin and oil paint wash and the basic paint job at the front.
