Thank you everybody !
To finish the painting, I've added the lips on the face (Vallejo 70982 cavalry brown).
The shoes are Vallejo 70941 burnt Umber
Few tufts of grass on the SHQ figures to link the feet to the base are painted Vallejo 70881 Yellow green with black wash and drybrush.
The french Helmet is Vallejo 70889 Olive drab
The french sailor hat is Vallejo 70899 Dark Prusia blue, some white stripes above and red 70909 Vermillion for others details.
The Legion hat is Vallejo 70883 Silvergrey with a white drybrush.
Officers have a sand hat cover (as well as English helmet : Vallejo 70 977 desert yellow) with a small square hole above to show the gold stripes of their rank, This can be located front or more commonly on the left side to avoid being a specific target for snipers. (my Grandfather worn such hat with cover).
The base of the figure is painted Tamiya XF59 Desert Yellow.
For the French guns I've added another black wash with a thin brush (0 or 1) just around the details and then a drybrush only on prominent edges/details Vallejo 70976 Buff. Wheels are Tamiya XF1 flat black.
Those 125 figures with 4 guns are finished (but not this WWII project), I can go back to my huge Napoleonic project now !
