Glow

1. Start with Corax White to the areas that will be green
2. Over the white detail, apply 1:3 Warp Lightning / Contrast Medium . Make sure to absorb the excess as we want to build gradually. Build in areas where you want it to be heavier. This should take a few coats
3. Make a glaze with Dark Angels Green and Contrast Medium . Use this to darken the darker areas on the glowing parts. Use roughly three layers.
4. Next highlight the brighter areas with White Scar
5. Take Tesseract Glow and Lahmian Medium and apply this over the green areas.
6. With White Scar again, just add a small highlight to the most promenient edges.
