Ivy... what kind of "Bow and arrow" 

Are we talking a simple longbow or recurve with nothing much in the way of fittings? Are we talking something like an improvised bow made from PVC pipe? Or something like a bundle bow? Or are you talking something like a compound bow with risers, string silencers, sights, and so on? Or perhaps are you even referring to a crossbow? What about a slingbow? (slingshot modified to fire arrows)

There are many different "bow and arrow" concepts out there. Also, quivers don't hide arrows. They are holders for them... So if they're 'hiding' 25 arrows, how many are they not hiding?

What kind of arrows are you using? Wood, bamboo, aluminum, carbon fiber/fiberglass? What are they tipped with: stone, bone, metal, and broadhead, target/field tip, or even no tip?

What size bottles of water? How many apples and oranges? Are the bottles full, or empty, or in between?

Also, this is Miami. Starting date is going to be June 14, which is late spring, early summer. The temperature is in the mid-90's with high humidity from daily or near daily rain, with lows in the eighties. Black on black on black with a leather jacket is going to be pretty hot. If that's what you want to work with, it's cool, but it's something to think about. 

Also, how does an unskilled high schooler (while a sociopath) become good with "Bow and arrow" who's spent most of her time in an urban environment? What opportunities has she had to pick up this skillset, and why? How did she keep this from being noticed by her father or friends, especially if she spends a good amount of time trying to blend in and appear normal? This skill is only mentioned in passing in "notable skills" but there doesn't seem to be much of anything in the history that agrees with it. 

None of my questions are meant to be mean, but the devil is in the details. Those were just some things that caught my eye right off the bat. I will be going over the other sheets with a pretty fine-toothed comb as well.
