Thank you. I did sort of copy it. I saw the cinematic trailer for Inquisitor Martyr the computer game. A Helbrute turns up looking like this. I knew right there and then I had to try and make one myself. Once I got started the other ideas just happened.
I've done a WIP and a blog post if you want to see the decision making or just see what the Helbrute it's based on looks like. Who ever designed the computer game Helbrute deserves a fair share of the credit.
