This is very interesting what you've done. It turns out that it's the methodology of many photographers. They sit in a place they've previously chosen for its special characteristics, according to what they want to achieve, and shoot everything that passes by. This work is like an investigation from which, of course, they choose the best shots.

That's really true!! some photographs once they found a good composition stay there and waits for the "Correct" person to pass by... my approach was different, i wanted to show variety in the same spot
