I like a lot the background of your army, I too incorporate tilean mercenaries in my army. I'm very interested to see how those Assault Groups german pikemen will fit next to the pirazzo's lost legion.
What model is this anyway, it is not lost legion.
The paintjob is decent enough for RNF troops, I wouldn't bother more than that, ( what is that green on his hands btw?) you have some 50+ more troops to paint, right? Better concentrate on the command group of the unit and the first rank, maybe.
His face is a bit odd, his eyes give the impression that he's happy to charge in the enemy? But they are convincing, so why not leave them like that. Keep up the good work
