The second "block" of the Necropolis is painted. I'm still working on the third block - building them takes way longer than painting (even though that doesn't feel quick while I'm base-coating the metal parts!).
I'm really happy with how it looks already though.
I've also re-painted one of my old Harrowmark trees - the free-standing one that's on one of the 1990s 60mm Adeptus Titanicus bases, that are only 2mm thick.
I stuck with the same colours as the other pieces:
- Halfords grey primer (spray) undercoat; Luxion Purple Contrast on the sand and the tree with a coat of Basilicanum Grey Contrast over the tree bark;
- a home-made green wash on the stone (a mix of blue-black ink, yellow ink, matt medium, and water, with a tiny amount of washing-up liquid);
- a light purple wash into the corners - made of Magos Purple, Wraithbone and water - to match the lighter areas of the Spearhead Sand and Bone board;
- a drybrush of Ushabti Bone over the sand;
- Ushabti Bone basecoat on the (single!) skull on the base;
- and finally, when everything is really dry, Magos Purple over the drybrushed sand, the skull, and some of the lighter areas (the Magos Purple/Wraithbone/water mix).
