Going with no-1. The tension between the horizontal movement of the upper ledge, sidewalk curb and road lines, balances nicely with the vertical movement of the people; and the variation of their poses keeps the movement going nicely. I will say that I would have picked no 3, but for the fact, that for me, not enough of the face is showing, and that is principal element in which makes the image. The dynamism of the city with a hip young person lands on his face, but it is partially covered.
