Thank you everyone for the supportive comments. The knights have changed just a little bit, with black crosses now instead of red. As for banners, I had a lot of fun painting that one, I'm now planning how to include more and more in my army. I'm particularly fond of this idea: Have a Nuln Gunnery School Banner set up behind the cannons, maybe as a turn counter, but mostly as an excuse to paint a cool banner that otherwise might not make it into this army.
