I've finished the Herald of Slaanesh on a Seeker and 4 other Seekers I had left to finish that are not part of the challenge.
The only Daemons I have left to complete are 10 Daemonettes. I had modelled two of these as Heralds of Slaanesh for part the of Challenge. But I've seen some good conversions of Warhammer Dark Elves Witch Elves in to Heralds of Slaanesh. So I will be popping off the arms and the heads of the two below and making the regular Daemonettes.
This will give me another squad of 10 to use.
They have been based and washed, ready for highlighting.
