The conversion was quite simple. I swapped the original head, which I think looks really silly, with the scarred Empire Flagellant head. I also replaced the sword blade with a FW World Eaters Meteor Hammer from the Rampager kit.
to make this model stand out from the rest of the army, I painted it in a new colour scheme. I chose the colours from one of the newer FW books. in this book some World Eaters, like Red Butchers and veterans, have painted their armour red. This is a step closer to what they will look like in 40k, which I find fitting to my army, since I sometimes use them with the Khorne Daemonkin: codex.
Yesterday when I took these pictures I also tried to make some short videos of this model, and many others in a 360 degree view! It turned out pretty good, but I haven't found an easy way to get them on my blog. They are however on my Instagram! Follow this link to see some cool 360 degree videos of my miniatrues!
This is the picture I found on Google from one of the Forge World Books. I think I will paint more World Eaters in this colour. It really gives the army some much needed variation, and it was a fun colour scheme to paint.
