SG: Cutting off the tips is a great idea. I will do that. Fixing the painjob is trivial.
Emperor's Children (Slaneesh) Force:Unlike Khorne and Nurgle this is supposed to be more of a shooting force. The core retinue is the same mix (again, DP on hold). The Rhinos are supposed to have something resembling warp amplifiers on top. The "boss Rhino" has a bit from my 40k Eldar box.

Support comes from some Noise Marines with "big speaker Rhinos"

and some Havocs with daemonically possessed Rhinos (some old WFB bits). The Havoc base is a blend of Noise Marine, 1st ed Chaos Missile Launcher and new Chaos Heavy Bolter models.

Daemonettes (GD held back as reward)

Beast of Slaneesh are the riders with a (simple) converted lord. The retinue daemon prince from the Warmaster range came with a second Slaneesh model that I am going to paint up as a more chaotic leader for the riders.

I don't really have any dedicated Black Legion vehicles/warmachines for the Slaneesh force because I am sitting on a huge pile of Slaneesh Knights of all types. I guess those go into the LatD list but I can use them as proxies for Defiler/Feral Titans for this force as well.
