Asshatter, I appreciate the apparent effort you put into your CS but there are a few issues:

[list][*]You did not PM your CS to me and get approval before posting it.[/*]
[*]This is not Israel, or Earth for that matter, so Krav Maga isn't really a thing. Knowing an equivalent is fine, but KM is essentially a mix of several martial arts with some added lethality. You were oddly specific with the fighting style, but then left the weapon training as "melee weapon".[/*]
[*]A thirteen-year-old did not master Krav Maga in two years.[/*]
[*]Kriss will go out of his way to recklessly save people at the expense of his own life, yet he apparently hates them and can't stand dealing with them. Not only is his personality contradictory for no discernible reason, but he has a meaningless death-wish. You went into detail on how he managed to meet his instructor, but barely mentioned the events that turned him from an idealist to a suicidal cynic-idealist.[/*]
[*]I specifically stated that the limit for firearms was revolvers. Every rule has an exception, but I can't very well grant one if the rest aren't followed.[/*][/list]

Also, I agree with Uffizi. It's better to be vague but informative with backgrounds so that you can fill in the gaps later for character development and filler.
