Yeah I've seen those! I was just wondering if they're gonna work on something much, much bigger. I'd be making banners waaaay bigger than those.
Sorry but i dont know any myself. But your Lannister style army sounds awesome Shame im a Stark through and through...
There are two reasons why I didn't do the Starks:
1) The colors are somber (grey on white). They won't be as visually eye-catching.
2) I picture the Northmen as a less fancy lot, and the Perry Miniatures are somewhat fancier, more Southern Westorosi than North. If there are good miniatures that could represent the North, I'd be glad to make a Northern army... maybe the Boltons or the Karstarks.
