I'm a huge fan of the 'your guys' principal, so I wanted to do some relatively obscure successor chapter that I could come up with my own paint scheme for, something dark with lots of blacks and reds. I play IG, so I wanted to go in the complete opposite for my next army, with a super assault focused army composed of elite troops.
I'll show pictures of the other three that I painted up in all different chapter colours, but I currently have an Intercessor and a Reiver in the colours and livery I intend to use for my custom chapter of Blood angels successors. Picked up a set each of the easy to build Reivers and Intercessors just to paint for funsies.
