Well I have been going over my Death Guard list and one of my favorite HQ choices has got to be the Demon Prince with wings.
I really liked the sculpt, so I went looking for one and Mike found it on the shelf at our last game shop stop, so I went looking for some wings that looked right and found these in a Reaper kit.
I thought the original head looked a bit thin, and wanted to go with a resperator or gas mask, so I used a fantasy Ogre head, and modeled the mask with putty.
painted him dark with lots of washes, and based on mixed rubble.
I am near finished painting him and I think he will fit in well with my Death Guard.
