Those are indeed Kabalites and Wyches. I like the colour scheme; there is some good depth to the greens and the flesh tone. Were they achieved with inks or just highlighting up?
Just some minor constructive criticism: the metallics look a little plain, maybe use some brown or black inks to dirty them up a bit and then pick out the raised areas with a bright silver?
Any plans to decorate the bases? A nicely finished base really brings the model to completion properly
Lastly, any plans for more Dark Eldar being painted? What models next?
