It would be far more cooler if you aimed at a more gory, bloodish colour dye on the armour for the classic World Eater Champion! I don't like the bright red colours you used on the figure, doesn't feel right!
This mini deserves a better score. The red could use more depth but come on, we all have trouble with it. Do you highlight up to an un-Khornate pink, or an orange so he doesn't really look red anymore? This has a lot going for it - the bone parts and the green blade look great! The base is plain, I would have done more with it.
