I built this guy yesterday using the Dark Imperium Primaris Captain in Gravis armor model but swapped his arms out for spare Lugft Huron arms and pinned the banner to his backpack as my take on the chapter master of the Astral Claws if he was a Primaris and I am happy with how he came out and look forward to painting him I am going to use the Lugft Huron head aswell but I paint helmetless heads in pins to glue to the bodies after all is painted up

Not sure as of the fate of my Astral Claws rules wise with the 9th edition starting up and the Space Marine Codex but hopefully ForgeWorld come out with something good to use

Edit: some reason when minimizing the image on FA it turns sidewise not sure why
