Thanks for the update.
The art is going to be the same like in Marengo no??? lack of photos from nap period made not possible use the PzB and now PzC Gold portrait system... but for example FWW uses a diferent art style and for nap series are really good art mods specially one serie using portraits from books (not the Osprey models, other diferent).
But maybe the only interesting thing for the stock art in nap serie could be add behind units the regimental flag if is avaliable and put national flag in a corner like an icon and something to made easier diference the infantry portrait from a cavalry portrait (maybe another icon with a horse head... no mafia involved
Well, good luck and expect see soon the title.
