step 1 as joe suggest I started to staining the model with createx transparent dark brown
step 2 I mix freestyle pale flesh- and off white and I thinned at 20% with alchol isopropilic and made a large mottled on the model
Step 3 I made a very very narrow mottled (circulare sense) with golden transparent raw humber and then with yellow oxide....then I follow the muscle line with freestyle olive green plus a tuch of dark green and then again over with golden shadow gray very very thinned
Step 4 I mist (90% thinned) the base color over the skin to omogenize.
Step 5 with golden transparent yellow oxide in a very light way traced the base for the spot
Step 6 I made the spot with freestyle black green than I spryed over freestyle transparent medium green (light in the lateral and heavy in the middle and on the back) and then I go over with golden raw humber
Step 7 cheking the making of scenes you can see in effect that the green is not so strong so I made I finale touch of freestyle nuance raw humber
thats all and sorry for my english and dont exitate to ask to me....It's a pleasure help thi community
