The Eternal Scream.
First off, I know Raziel is supposed to only have two fingers and a thumb. I always thought it was weird. And since it's my redesign you can go fuuuuhahaha I'm just playin' I don't care. I like to imagine that rather than burning in the abyss for centuries to gain his spectral form it was just a short period. Maybe just a change to be compatible with that realm and the Elder God simply ripped his throat out...through his abdomen to give him the ability to eat souls. Also when he is in the physical realm his form isn't stable and you can see it deteriorating in real time. Oh the next gen particle effects that could've been.
Edit:I updated it with a larger image so you can look at the downloaded version up close.
