Pre Heresy / Fallen Dark Angels

Me as so many others bought the Betrayal at Calth game for the Mk IV armours and a starter for a 30k force. I have always liked the Dark Angels since the first Angels of Death codex and since I already have a substantial Pre Heresy / fallen Dark Angels force I decided to do a quick paint test on one of the Mk IV armours to see what it would look like. I added some blue white checkers to the paint scheme but otherwise I kept it in-line with what I already have. I put it in a line up with the other armour types already in the force (it is in the middle). I think it can work, just need to sit down with the bases.
