Looks incredibly cartoonish and paperish! Where are my xenophobic religious fanatics-space nazis exterminating entire races for the Imperial Truth! Back in the days of old, of old fluff and the whole things, I really thought that it would be better to live in the Eye of Terror than in the Imperium and all Primarchs (even loyal ones) werent some damn saviors and heroes but blood-thirsty demigods-tyrants with monstrous ambitions who ordinary people of the Imperium would rather tremble before than praise and worship
well they are only doing what the raven guard did during the horus heresy, melding primarch and space marine DNA to create super powered marines...
