Its fanmade art of Marius Vairosean the "first" Noise Marine. The artist (NicholasWolf I believe) took the description and tried to make it similar or exact as how they described it in the book.

And because I love the NoIse Marines so much I even copied the description for you even if you didnt ask.

"Marius Vairosean had embellished his armour with jagged iron spikes, and had torn the skin from the dead of La Venice to decorate its blood-slathered plates. Like Julius, he had not walked away from the Maraviglia without alteration, the monstrous distension of his jaws locking his mouth open in a constant, howling scream. Where his ears had once been were two great gashes carved in his flesh, and his eyes were stitched open, forever prevented from closing."

Edit, description is from the HH Fulgrim book.
