Obviously these are not based off of GW Raptor models for Chaos. I’m not a big fan of how those look and metal models are much harder to work with. I built my Raptors from a Space Marine assult squad with additional bitz from a CSM box, Iron Warrior upgrade bitz and Chaos Knights (fantasy range).
I have decided to use the GW Iron Warrior shoulder pads for my entire army both because I like the looks of them and I don’t like using decals.
