Looking super Strelets. I really like the variety of faces, 'kit' and especially headgear—the be-tricorned fella is a ripper.
As a contrary view to Alan's, I like to have the option to paint a flag. It can always be removed to replace with a paper version, or even a bit of metal/foil from the top of a bottle of wine, which someone put me on to years ago. Enables the flag to be moulded after painting.
Aside from any examples, the pipe needs to be exaggerated for best modelling effect, IMHO.
Your curent output 'on steroids' is wonderous! They seem to be taking a while to reach us in the antipodes though...
