Hey there! I really like what you have so far, bravo.
That indeed is a big unit of knights. I usually don't go for the painted armor look, but it looks good on those guys. Give those horses some love, and that unit will go from good to great.
I really like the simple hammer conversions on the greatswords. It's things like that make your army yours. The brass armor on them looks good next to the red and blue.
Finally, I am considering painting an army in Altdorf colors myself, can you answer a few questions for me?
1. How does that red basecoat? Does the foundation paint cover in one layer? I am trying to find a good way to paint red now, all I have is some cheap craft store reds, my old GW ones dried up long ago, and it takes 5-7!!!!!! layers to basecoat with this crap. I would love to see a WIP shot of the different stages but that might be asking a lot lol.
2. Are you washing the blue with Devlan as well? The tones seem very similar, which I like.
Oh, and don't sweat the Halberdiers. They aren't bad as a troop choice, and I think you'll see more of them in 8th than we have in years.
