I have to say I only really like the plain white one, the others don't look very good. At a distance they aren't bad, but close up they look pretty poor, especially the gold one, the white and gold just dont mix well, it isn't a great colourscheme. Perhaps I should have given that one another wash. Well, I have learn't my lesson now, my other squadron of firestorms are already done but when I paint my Sword squadrons I'm going to stick to the simple colourschemes, one main colour for the body with decent shading and highlight but lay off the gilt edges.
