Here are two more quick projects:
German and Austrian Artillery
German and Austrian Uhlans
Very nice. Maybe you should consider to use a grey, that is a bit darker. The prewar feldgrau uniforms that I have seen, use a Grey similar to the "Steingrau" of the uniforms of the east german Nationale Volksarmee.
I made some US Army Uniforms from 1861:
first line: full dress uniforms with stiff hat and epaulettes of a soldier and a Sergeant. The epaulettes came soon out of use in the field.
second line: Service and campaigne uniforms. The third uniform with the short jacket is a informal everyday uniform. Maybe more will follow.
