Following the exarch shown some time ago here, now we've got a trooper from Orlando's Dire Avengers squad. I'm not sure but looks like the right arm has been converted somehow in order to keep the shuriken rifle upwards. The left hand bears an imperial combat knife (don't know if catachan or from space marine scouts) painted like a magical/powered/whatever blade. i really like the soft purple gradient.
The colour scheme is the same of the exarch, so blue for the armour and red/green for the crest, representing the craftworld colours.
