looks great but i always thought that the or at least the Cadians, which include these guys, and the drop troops, always looked way too advanced for what the Guard are supposed to be which is a vast mass of expendables; i always thought they should look as if their home planets, the imperium itself, really didn't invest all that much in them individually. Just enough to make them deployable. The valhallans, Catachans, the Krigers, and the Steel Legion, all have the sort of look I would more associate with the guard. The Mordians are alright i guess.
I forgot about the Tallarn guys. Those guys look right in my book too.
