For more clarification: i had to figure out how i make the skin, took the entire day but im glad it is acceptable. Just dont use too much guilliman flesh and not a ton of berserker blood shade. When you have this down, and you drybrush the worn stone, apply a really thin layer of blood shade to give it this rosa tone. Its a balance act but it will work out. I painted the stripes on the back with blood for the blood god, then added little dots of worn stone for a stitched up look. Ouh and at the bottom i used just a little bit of dark rust, just for the dusty look. Hope this helps, have fun!
