I liked the previous more.
This version looks more... "quiet", i mean, it seems a dead man implanted with some kind of robotic parasite that is able to control his dead body.
The other seemed a living person that had been just violently torn apart and experienced fully all the pain and suffering of being infected by a merciless parasite.
And i think that's what is shocking about the subject, so i liked the first, bloody version more. ^_^
You have a lot of talent, by the way. I'm looking forward to see the project where this character is going to be included complete. :D
