Turns out I'd criminally forgotten to post my squad of Warlocks. I must have finished them a couple of years ago and they've had a few outings on the tabletop.
I'm quite disappointed by my choice of colours for them. I feel I applied the principle that they sport the colourway of the Craftworld too rigidly (in this case, a very early Rogue Trader-era scheme). This has left them rather dull I feel. When these sculpts first appeared, the Studio Eldar army was a gloriously multi-coloured affair. Not only did each of the Aspects having its own colourway, each individual Warlock sported different livery. This gave them a sense of being special as befits their background. If I do a second unit I'll go down that road I think.
Actually I want to make any future units of Aspect Warriors a bit brighter and more varied. I've gone down the 'grey' route too much for the Dire Avengers I feel, but the Scorpions and Spiders are a bit brighter and that's something I want to pursue.
