This wonderful model is not converted: it's a Forgeworld Nurgle drednought. I've (gladly) painted it for the 25 years of a friend.

And this is a Tyranid Hierophant Titan, painted for the 26 years of the same friend. You san see it bigger here. Yes, the model laying under it is a human at the 28 mm scale...

Always in the tyranid range, this modelhas been completely converted by a friend and painted by me.

... The same one, nearer.
