Rating: 7 Banner looks great! the rest of the model is lacking greatly. I think if you put as much time into the actual banner bearer as you did for the banner itself, I would have rated this at an 8.
Rating: 8 The banner and cloak are amazing! But the armour sort of looks like mustard? Maybe some highlights and reflections would make it not so bland.
Rating: 8 The chips in the armour look a little big. I think those dark browns (like scorched brown) work great for most colors, but in your case you might want to weather with a slightly lighter color.
