I know there are a handful of civilians, but it would be nice to see some in 'everyday' type poses not just the angry mob ones. You know, towns people, market scenes, black smith shop & figures, shepherd and ship (I thought I saw this one somewhere), etc.
Some more thoughts inspired by the above words by Correus.
All the above would be nice, but what about some troops with tankards, seated types (mainly cavaliers ) drinking, gaming & with a wench on knee, a tavern wench or 2, and an irate barman, some fellows in a stupor, some staggering supporting another (could double as a casualty marker) or be used with the surgeon set, a lady of the night vignette as seen in the Battle of Worcester write-up, etc - all of this could be used in scenario's where the camping/billeted army is surprised by the enemy - I'm sure the historical examples spring to mind. The new 4Ground buildings would be ideal for this, too.
The other types would be siege pioneers, miners, fellows shovelling and wheeling barrows of dirt, shot or barrel,etc and an officer or 2 with a map, pointing, using a telescope, etc.
Many of these could be used in several periods of the P&S era, so again good sellers.
