I have really been enjoying painting these Pallid Hand Plague Marines for my Death Guard Kill Team. Here is how I painted most of the main elements.
Basecoat the armour with Wraithbone . I also primed with Wraithbone , to make to process quicker.
Wash the armour with Skeleton Horde , thinned with an equal amount of Contrast Medium .
In particuarly deep recesses, I like to pop a little Agrax Earthshade , to define them more. You could also just use a thinned darker brown like Rhinox Hide .
Edge highlight the most exposed edges with Wraithbone .
Add specular highlights to the centre of the previous ones and on pointed corners with dots of a pure white (like Vallejo Dead White ).
Add thin downward lines with Rust Streaks by AK Interactive.
Shape the above lines with some white spirit on a brush. Making them thinner and adding a nice natural looking stain.
Basecpat the armours with Deathworld Forest .
Wash with Agrax Earthshade .
Edge highlight with Death Guard Green
Add small highlights of Nurgling Green where relevant.
Finish of by mixing some Pallid Wych Flesh into your Nurgling Green and adding specular highlights to points and corners.
Bronze Armour Trim
Basecoat with Balthasar Gold .
Wash the metal with equal parts Agrax Earthshade and Aethermatic Blue .
Add any edge highlights you fancy in with Sycorax Bronze .
Finish highlighting the metal with small specular highlights of Stormhost Silver .
In areas where the previous wash has dried and collected, pop some thinned Sotek Green .
Put very small amounts of Nihilakh Oxide within the previous colour. This represents the most oxidized parts.
If you wanted to add a little additional "pop", consider adding dots of pure white in areas where oxidisation would have REALLY built up.
Basecoat with Screamer Pink .
Wash the tentacle with Druchii Violet . Don't let it pool too much.
With a 1:1 mix of Screamer Pink and Pink Horror Horror cover most of the flesh with a thick glaze. Pulling paint towards the centre always. Paint everything just outside of recesses where the dried shade has dried.
Paint a smaller area with pure Pink Horror . Use the same technique as above to ensure a smooth transition. This time go over around two thirds of the area, painting higher to simulate where light would hit and adding the illusion of depth below.
With a 1:1 mix of Pink Horror and Kislev Flesh flesh paint an even smaller area, pulling even closer to the centre and higher.
With pure Kislev Flesh paint a very small area. For some tentacles I add this highlight as multiple small lines to add texture.
Optionally, add dot highlights of Flayed One Flesh to the points of tentacles and the centre of the previous steps highlights.
Basecoat with Rhinox Hide .
Cover most of the bone wit a couple of coats of XV-88 . Leave points at the bottom and pull the brush towards the tip.
Mix XV-88 and Ushabti Bone 1:1. Now repeat the above step, coverring less area.
With pure Ushabti Bone do the same again, you should now be adding these like a chunky highlight towards the tip.
Coverring an even smaller area, highlight with Screaming Skull .
With a pure white (like Dead White or White Scar ) highlight the tip of the bone and any odd corners that could do with a pop of brightness.
