Very impressive.
2 minor points:
Usually schuetztruppen had slouch hats , while you have used the Asienkorps, which was in Palestine.
the command units are a little belgian.
So, the best choices are:
Brigade games, incl. Von Lettow-Vorbeck and Tiger miniatures command unit.
Sailors: Brigade game they have 2 packs of german sailors, 1 of command and one packs sailors with HMG.
