I'm working hard on improving my 6mm faces too now, it's just a matter of 4 tiny touches, down the nose, on the chin and a fine stroke down both cheeks. It gives a reasonable impression of a face I think and is better than a 'blob'.
I'll replace the 'wonky' flag tomorrow I think. Overall I'm well pleased.
Commands & Colors Russian Expansion tells me Russian Line are 3 blocks, have good firepower and may ignore one flag throw- which I guess reflects the very stubborn fighting ability of these troops.
I'll be painting units in both greatcoats and full dress as well as Grenadiers, lights etc as things progress.
