Red Armour

1. Spray with Red Primer German Red Brown
2. Layer with the first red Scarlet Red leaving some of the deepest recesses from the German Red Brown layer
3. Shade with thinned down Petroleum Gray not quite a wash but thin so it runs nicely, this should cover most of the primer now.
4. Mix 50% Scarlet Red and 50% Bloody Red and layer up again based on lighting - Pick the volumes from lighting doesn't have to be perfect.
5. Layer with only Bloody Red making the areas smaller and smaller
6. Highlight with 50% Bloody Red and Medium Orange same really small area this time.
7. Highlight with a small amount of Medium Orange
8. Final highlight with Ungor Flesh these are dots and tiny lines where you can.

White

1. Basecoat with Petroleum Gray
2. Add in some Heavy Warm White to the Petroleum Gray and highlight. All the way up to pure Heavy Warm White
3. Add some White into the Heavy Warm White for final highlights
4. Glaze back down with the Petroleum Gray - This is an odd step, it doesn't have to look perfect, as shown in the main picture just get the volumes right from about 1ft

Yellow Helmet

1. Basecoat with Heavy Warm White
2. Layer over Imperial Fist contrast
3. Wash with Reikland Fleshshade in the deepest recesses
4. Highlight with Yriel Yellow
5. Add in Ice Yellow to the Yriel Yellow and line highlight
6. Add chips with the Petroleum Gray

Metals

1. Basecoat the silver with Black Metal and the bronze areas with Decayed Metal
2. I used some thinned Petroleum Gray to shade the Black Metal but you could use any black wash.
3. Then Wash the Decayed Metal using a Green Oxide but Nihilakh Oxide or a Jade Green would also work here.

Skin

1. This is easy! Advanced Flesh Tone as a base then keep adding in Heavy Warm White for highlights and done.

Lens

1. Basecost with Dark Sea Ben or any deep sea blue.
2. Add in some Green Oxide or any Jade into the blue and make a cresent shape.
3. Keep adding in more Green Oxide and making the lines smaller
4. Add in some White into the Green Oxide and repeat, leaving a dot of white on opposite sides of the lens.
