meh, perfection perfection whatever - i like them all for what they are!
i specially like the first one - she looks genuine there and i dunno why but because its not lighted in the correct proffesional perfect manor (sarcasm...? lol!) it gives it more character - makes it feel more like its just you and ya girlfriend out for a walk playin around with the camera - more natural, more real, atleast to me it is anyways.
the third one i think too - looks like your both just waiting to cross the road, and you quickly take a photo of her and shes like "who the **** are you?!"
im no proffesional - but for me personally, sometimes photos should just be enjoyed for what they
