Good stuff. My own lads are in yellow, although Imperial Fists - at least that means I get to avoid the checkerboards! Although I like you decided the shoulder studs all needed picking out! You'd think after all these years I'd know when to quit. As a youngster I went for Blood Angels, but was never very good at painting red so decided to tackle the next nightmare colour yellow!
Liking the battle damage on the armour and the banners are a nice touch, good to see some Marines bannered up.
