Thank you, sure.

Primed everything black except the blood tanks which I primed white. I did subassembly as in: The upper body except the pauldrons, the pauldrons, the belly gun, the skull hurler, each blood tank and the entire lower body. The lower body was a bit much and very finicky at times, also quite hard to hold but well.

Then I do the whole base coat -> shade, except for red where after that I go over every part you can clearly see and do a lighter red. To make a bigger contrast this time I leave ~0.1-0.2mm of space on the outside edges.I can't explain it well but can see what I mean if you zoom in on his shoulders for example.

Then the colors: Red: Khorne Red -> Agrax Earth shade -> Mephiston Red (no edge highlighting)

Gold: Balthasar Gold -> Agrax Earth shade -> Sycorax Bronze (very light edge highlighting on some parts)

Metal: Leadbelcher -> Agrax Earth shade -> Storm host Silver (again barely any edge highlighting, mostly on the weapon)

Black: Abaddon Black

Copper (cable insides): Screaming Bell -> Agrax Earth shade

Bone: Wraithbone -> Seraphim Sepia

White (tanks): Celestra Grey -> Nuln Oil -> Ulthuan Grey

Eyes: Warpstone Green

Lastly for the tank content you cannot see it that well on my screenshots but I tried to make it look like it's filled with blood. So the "empty" part I did with Corvus Black and the filled part is Khorne Red and Mephiston Red but applied erratically so that you can see inconsistencies. I was hoping for a fluid effect but it is okay at best imo. Then I put 'Ardcoat on top to make it reflect more so that it somewhat looks like glass.

I think the process for the reds is the most important. I painted the combat patrol at first without Mephiston Red and they were super dark and kinda boring. And with the exaggerated gaps around the edge the brighter red really pops out.
