Thank you both

Regarding these latest tiles, some of the height variation will close-up as the tiles are surfaced and so in-game it will mostly be about how the depressions (the ditches and the shell holes) help or hinder an attack on the town..... Will they slow or fracture a charge or provide locations for jump off points and covering fire, etc.? Let's hope the rules work!
As an aside, I was laid up most of yesterday and did a heck of a lot more research (lots more time for a little more info) on uniform colours for the Minerva crew ..... subsequent to which I decided to modify the figures slightly so that there will be two as cavalry# and two as infantry*.
#Edit: the commander and driver will be clothed as men from 2eme Régiment de Chasseurs à Cheval, who in 1914 were garrisoned at Mons and whose uniform is I believe worn by the crew of the 1:1 Minerva replica that was built for Belgium's 2014 '100th anniversary' commemoration events.
*Edit: to be more specific, the gunner and loader will be depicted as grenadiers, in a nod to Lt Charles Henkart (who had the first two Minerva armoured cars made from his personal vehicles) who I have read was a grenadier officer.
