Nurgle? from a Tzeentch champion????

My Plage bearer test model. I used Utheran grey then Earthshaded it to make it a dingy pale skin base. THen useing nurgling green (hard to see on his left arm here) but layer that to help with the putrid colour of flesh. The wound is done with Orange, and red washes, followed with wild rider red highlights. A mephiston "scab" will go on tonight to help the bleed effect.
