Bonjour Brian,
Well done!
The facing colour works very well.
I've got some of these too but they've yet to fight a battle!
I use thinner bases - 2mm MDF - which I find allows them to "sit" on the table better and I paint the edges of my bases to match the ground colour.
Will do some pictures when I can.
Note that you're painting Spanish cavalry next and I look forward to seeing them.
Cheers,
Paul
