After KrautsScientist's awesome suggestions, I made a few improvements to the champion. I replaced the axe with a sword from the Tzaangors and used a piece of a Daemonette's whip for the pommel.
Then I added a second breastplate. I also tried to scuplt some more ornamentation with green stuff. But sadly that didn't worked at all :-( .
The necklace of the Infernal Enrapturess was placed between both plates.
And a second spike was added to each leg.
I decided to keep the big banner on the backback and went outside to prime that guy.
Thanks a lot for your visit, feel welcome to comment and stay tuned.
