The model is made by the Polish alternative manufacturer Maxmini. It’s a three-part resin model about the size of a common Terminator. In fact I could see usage for the model in a Nurgle-themed CSM army as well.
A simple back shot. The “blood” is Vallejo Water Effects combined with Vallejo Gore Red -paint.A scale shot to show the size of the model compared to the giant Kromlech Rotten Butcher I featured earlier.
