Very nice looking units, I appreciate, the effort you put in creating interesting unit champions, who add a certain interesting accent. Also like the banners, especially the blue towergate. I might copy that for my army, which is also mainly Middenheim/Talabheim...
..on the side note: I noticed how all the faces have a slight yellowish hue to them. Is it because of the lighting or you painted them that way?
Good work thou!!
