The only thing missing from your sheet is your attack damages. You've got the dice, but putting in the pluses makes my life much easier, since I don't have to calc it out whenever you try to stab someone. They should be:
Bashing: d2 + 10 + 4
Slashing: d10 + 7 + 4
Piercing: d12 + 5 + 4
Technically, you should have at least one mutation based on your background, but I'm just going to say that you got all of your flaws from the corruption and your Talents evolved naturally with your powers. You're going to be starting in Artmirst, with demons chasing you already.
