i think the first would be better if you would have pointed the camera more upward while squatting down. that way the lines would be straight, plus you'd see more of the person in the shot and still keep enough of the ground in the photo to add texture.
and yes, i would have liked to get more people in the photos but the nature of this place is you cant really hear anyone coming or going and they just sorta pop out for a brief second....you would not believe how many shots of legs disappearing to the next grid over i have...
