I saw this and the other war memorial you put together and they are absolutely amazing. Also a brilliant idea for the fans out there. I would love to see a memorial put together honoring Loken and Torgaddon in their fight v. Abbadon and Little Horus Aximand.
Or perhaps Ahriman v. Amon from Ahriman:Exile. That would be pretty awesome, especially if you could model those two where they were surrounded by Thousand Sons watching and waiting.
One more? Nathaniel Garro v. Grulghor on the Eisenstien, pre/post warp translation (per Flight of the Eisenstein)
Definitely going to have to keep my eyes peeled for more of these. Awesome-sauce +10/10
