This is my conversion (still needs to be finished):
I've used:
- 40k starter kit chaos cultist champion body
- Empire Greatswords champion hat (with an added cylinder)
- 40k bits cross, probably Dark Angels bits (honestly I don't know where is it from or how it's called)
- Empire knightly orders hairy head
- Empire Greatswords torso
- Empire pistolier arms
- High elf spearmen dagger
The chaos symbol still needs to be shaved of and I need to sculpt a codpiece.
