While I am happy to see you Mortimer, I have a question about your character.
He is very badass and we do need some of those in a zombie apocalypse, but could you maybe tone it down just a little? I mean taking his friend's skull and putting it on his own head would work in another rp, but it doesn't seem very realistic for this one. 
The picture is absolutely fine. I juts didn't want drawn images or anime because this isn't going to be a cartoon. But if it looks real then it's fine.
I like the fact that he is a medic because we are definitely going to need one.
