My main idea for the Vlandian sergeant improved armor:
Basically a dismounted late 12th - early 13th century Western euro knight plus that Vlandian hood which makes little sense when you wear such a heavy helm but looks cool and adds something to the whole gear aesthetically.
The vanilla transitional helm looks quite bad imo, mainly because of those weird and unpractical eyes slits. It could be improved, but I decided to go for a different helm (which is mine). I'll change it though, by another one inspired by an
old Victorian early helm concept that I have to turn into a 3D model first. The concept is probably historically inaccurate, but I think it would perfectly suit the Vlandian sergeant for several reasons.
The vanilla surcoat looks good, but screams 13th-14th century so I couldn't keep it.
Will explain all these choices precisely in my complete post.
