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?
