Nurgle Rhino

I have finished painting my Nurgle infested rhino for my Plague Marine Squad. The giant Nurgle symbol on top was made with bases and spikes from the chaos vehicle ram. This idea was not mine, I saw someone else had done something similar on another website just cannot find the link at the moment. I just need some skulls or something to add to the centre of the bases.

The Rhino was painted the same was as the Plague Marines. I've used green stuff in various places as well as the Forgeworld Death Guard doors.
