I'm sure the first thing you notice on him is the crab claw which came courtesy of the daemon princess I ordered a little while back for my daemon army before I actually got Babylon. I wanted to give it a chitinous look though so I decided to do it daemonette hide and then hit it with a secret weapon purple wash which I feel complimented it rather nicely.
I feel maybe I could have added some more metals than silver to this but I'm not sure it would work out so well, the black fits with what I'm going for (again Slaaneshi Imperial fists) but I feel I could have thrown some gold in there somewhere.
The horns were from the Tzeentch banner of the CSM box, I think they add nicely to the model itself, and I hardly see any daemons with more than those two derpy looking ones. Honestly though I would have loved it if I had an extra fiend of slaanesh head to swap out, I think it would have looked pretty good on a daemon prince.
Now for what most of you no doubt came for.
As I'm not done with My CSM army I have decided to do this, a giveaway every week until I am finished. Standard rules, email in the comments, I pick a winner and send them an email for their contact info. Good luck, See you folks next week.
