One of my favourite images. This is a Space Marine or Adeptus Astartes Chaplain from the Black Templars Chapter. His wielding a power sword in his right hand and a bolter in his left. You can tell his from the Black Templars because of the black cross on his left shoulder which kinda looks like the contemporary Maltese cross. His armor is more intricate then normal space marine armor so its probably artificer armor which is common for chaplains. Furthermore he has a rosarious above his head and his helmet is skull shaped another indicator of a chaplain.
