(NB: I put up the list of Perks and Flaws with their costs/bonuses.)
Vigor 2: makes your PC slightly ie one point more difficult to stun (stunning is the lightest form of damage a character can get)
Reflexes: increases your DEX resistance modifier by one point (typically, this makes you harder to hit with a ranged weapon when you know you're the target, but it might come into play in other situations)
Observant: adds a bonus of one to any Awareness-perception checks
Danger Sense: adds a two-point bonus to Awareness-intuition checks
(I notice you have the Awareness broad skill only; the above two perks will work with this skill, but they won't be quite as effective than if you had the proper specializations.)
(NBB: max of three perks)
Obsessed: generally, this flaw means your PC has some sort of "trigger" (a person, place, or thing we have to determine before the start of the game) that possibly (the more points you get from this flaw, the more likely this possibility is) causes him to forget what he's doing or focus entirely on the trigger instead of the matter at hand (no matter how desperate the situation). This is very much like James Bond's very well known reaction to women.
Poor Looks: basically, what it says on the tin: something about your PC (and it doesn't have to involve physical beauty) causes a one-point penalty on any PER checks wherever the flaw might be noticed eg having this flaw involving nose-picking won't matter if, for example, the person your PC's interacting with is blind (until someone tells the blind person about said nose-picking)
Dirt Poor: first, starting funds will be _way_ lower than anyone else who doesn't have this flaw; second, your lower-class background sticks out like a sore thumb to those who care even minimally about that sort of thing eg people of higher social standing, causing a one-point PER penalty in such situations; finally, the flaw creates an NPC to whom your PC owes money and who needs to be paid regularly (or something bad happens)
