Warhammer Underworlds Garrek's Reavers pt1.

I took these pictures at the end of September, that seems so long ago now. I wanted to further explore what I'd done with the Stormcast but more fantastical. The bases got a rough pale blue base.

I then applied a fair bit of purple shade and also green glazes to make it quite ethereal.

Here's a close up of the shading.

I then drybrushed the base to pick out some highlights, might have lost some of that range of colour.

And now I'm stuck as I can't decide what colour to do the piles of sand/dust on the bases. Brown seems so dull, glossy black? Or yellow? maybe I should paint the skulls so there's more context. 

I've an interesting take on the rest of the colour scheme, perhaps I should block those in too for the full effect before I pick the colour?
