Javert as an adjutant guard in Toulon (in what I THINK is the period accurate uniform). As far as I can tell his job would have been to keep watch over a group of around 400 men while they were working. Presumably he did this from an elevated walkway along the walls to get a proper vantage point.
I imagine the sight of his piercing ice-blue eyes underneath the black brim of that peaked cap would have been quite unnerving to convicts and other guards alike. I figure just like his top hat later on he would keep the brim pulled down pretty far.
I assume he has a cudgel, because what idiot would make a prison guard go around unarmed, but I didn’t see any weapon in the reference I used, so let’s just say he’s holding one behind his back. He still has long hair, but you can’t see the ponytail.
(He looked so young when I was drawing him, but then I added facial hair and wow it aged him by like 20 years. He’s meant to be like … IDK, 23 here.)
