[@Narcotic Dollie] 'real world applications' may be a not of a stretch. I was enjoying the personality until I got to that quirk. Is there any reason why she has that particular reaction instead of some other mental scarring? I don't particularly like the idea of potentially showing the party a dramatic death of an npc or comrade and have some giggling in the background. 

Regarding her background, again, not a huge fan of the laughing. Also, how was she able to overpower an orc on her own? 

'anti' skills need not be mentioned, their omission implies the lack of skill. As with untrained skills. If they don't have any knowledge of the skill, inclusion is unnecessary. 

Equipment is fine.
