Yeah I think they would be a fun unit to paint. Unfortunately, or fortunately depending on how you look at it, my friend and I are splitting painting duties by faction between our two sets. I do Starks, and he gets the Lannisters.
One tip. Not sure if that’s a wash or paint around the dogs on the banner. If it’s a wash that bled over, I’d recommend putting the wash on the dogs before painting the yellow, so you can clean up any edges. Whatever wash you use on the yellow should not effect the much darker black, if you bleed over the other direction.
