These look awesome. I wish there were more heads with hair plumes like these
Wh40k went full circle and became WHfantasy
Does it look cool? Yes. Does it fit W40k's universe? Like a skaven in a spa.
Take a look at the Dark Imperium cover ;) I think the 30k style rather fits the Ultramarines. 40k grim dark design like clean cut Primaris rather fits a chapter like the Raven Guard.
Is that the... Eight spiked star of chaos undivided on their shields? HERESY!
