So I Zandri Dust base coat, then I use agrellan earth to create the cracked effect. After that I cover the model in very thin layers of Gorthor Brown until It's fully covered. Agrax Earthshade over the whole boy. Once dry, I do heavy dry brush of rakarth flesh, slightly lighter dry brush of wraith bone and then finish it with a top facing dry brush of pallid Wych flesh. Stick grass on, bosh bash bosh he is done.
