When doing the highlights, paint the face first, then the hands  and feet, then the rest. All the time try to leave a little of the  shade colour showing in the folds and creases. The nose for  example is really just a stripe with two dots either side at the  bottom. Also try to define the main muscle groups, chest,  biceps, and areas like shoulder blades and collarbone. With so  much flesh on show it is worth doing a little more work to  really bring out the massive physique of the model. The flesh colours were as follows. GREEN SKIN 1. AP-WP1110 - Army Green plus about 10% AP-WP1124 - Oak Brown  just to take the edge off the green.– 2. The above plus about 10% AP-WP1108 - Necrotic Flesh. 3. then more AP-WP1108 - Necrotic Flesh, about 10% 4. then a switch to adding AP-WP1102 - Matt White, just 7%. 5. and then more AP-WP1102 - Matt White, again not more than 5%. 6. and finally still more AP-WP1102 - Matt White, less than 5% .
