For my thaumaturge warband I made a few reinforcements. The warband is a band of witch hunters, who's entering Felstadt to save it from bad magic. Here's the original full warband.
Crossbow armed shooters are more in line with the theme than bows, I've made these with Oathmark humans, and warhammer bits (probably Empire and Brettonia). I've also painted them in the colors I'm using for my Guilders: A Life In Shadows and Oathmark humans. Same army and it'll let me reuse many miniatures across that.
I also gave these guys swords (so they can work as marskmen) and backpacks. My frostgrave soldiers are always carrying all manner of gear.
You should really check out Guilders: A Life In Shadows. It's my main project these days.
