I'm really sorry to answer 3 months later, but i didn't get(or see🤐) the notifications!
Sorry again!
For the wood:
-base: rinox hide
-steel legion, with the few first strokes very thin.
-then steel legion+bone and steel legion+++bone for the "lines"!
Masks:
base: steel legion+very little black
-steel legion
-steel legion+bone
-bone
-thin glaze in certain spot with warpstone freen
I used the same method/colours as the tree-revenants!
So the light wood it's like above, and for the dark wood:
-base: rhinox
- rhinox+warpstone
- warpstone
- warpstone+ushabti bone(more bone of course!). And on some branches a glaze of yellow.
For the dots here and there: red+rinox and then red and red+yellow
For the "greyish" part: rinox+a light grey (i think i used the mechanicus grey, but not 100% sure), then 2 more "steps" to go full grey,
And of course the khorne blood for the resin-like.
Once again, i'm ashamed to respond with so much delay, I hope in some way that this is still useful!
