Although not my original idea, I created a marker to show shock. Each unit will have a marker like this:

When a unit receives any shock, the amount is shown by adding a dice into the recess like this:

The difference in dice colour allows me show when more than 12 shock points are accumulated, by making the red dice show 2 points of shock for every pip. Thus we can show from 0-24 shock points.
As for additional figures, here's one I painted earlier. I present Bertram Oliphant West or as his friends call him 'Bo' West.

The figure is converted from one of Mason's ranges with a French Foreign Legion head transposed and a neck covering modelled from green stuff. It was originally painted for the BLAM painting competition.
Next up are Lady Jane Ponsonby and Cork Tip.
