Thanks gentlemen.
The shields are transfers scanned and reduced to fit the figures. It's a bit fiddly to do but it looks nice especially at a bit of a distance.
The various ranges fit together well enough I think and you can never have too much variety. A few new command stands and a couple of elephants and Parthians can pass muster for Sassanians. So if you are tempted to do Belisarius's army you would pretty much already have the opposition.
