I've been playing around with the new plastic daemon prince kit a lot recently and have a couple of new ones. Similar styled models in the Slaanesh theme.
Keeper of Secrets
I hit a couple of bits sites to get some trygon/mawloc claws, a couple of seeker banners and a second left arm for my keeper. It has two daemon prince torso fronts welded together (one spare from another kit) to lengthen the body and accomodate the keeper's four arms. I then filled in the lower back as I only had one rear torso.
I have him looming over a downed jetbike in recognition of the slaanesh-eldar connection, although its hard to get a good photo of the soon-to-be-dead rider.
Daemon Prince/Fulgrim
The other one was mainly to see if I could get the wings to do something a bit different from the standard pose. I cut one of them along one of the fingers and then bent the wing round so that it's shielding his left side, filling the gap with green stuff. I also added some green stuff hair to change the face.
I was sort of thinking Fulgrim when I made him so I'm going to paint the dead marine in Iron Hands colours. and I added a winged claw to the banner as a vaguely Emperors Children-like symbol
