This concept was going to be one of 4. The person never got back to me, so I'm posting it here. As you can see, there was no back view and it's still a bit unfinished (mainly the blade). There's also no front view for the helmet.
The concept was based heavily from the Angels of the Angiris Council in Diablo 3 along with the Knights of the Round summon in Final Fantasy 7.
Perhaps I will end up using the idea in later projects.
I'll have to take a look at it!
