me... my 2 cents...
#1: your body posture looks a bit hesitant/tentative... i'm sure you're just trying to cover yourself b/c of what you are/aren't comfortable showing (which is completely fine), but that's just the vibe i get
#2 & #3: how can anyone really choose between these? pic #2 is great b/c of your hands covering/massaging your boobs, but #3 is awesome b/c your hands are out of the way so we can see all of your amazing boobs w/those perfect nipples... plus your abs are great in both of them... if you FORCED me to choose, i would say #3, but i would be more than happy with #2
(of course, fortunately, we get to see all three of them, so i think it's safe to say that we win all around

)
