The last attempt was the good one. The first two shooting of this sequence were failures. The cause are two beginner's mistakes. The first one was ruined by a wire masking a leg and the second one was to shoot pictures with a closed door opened while shooting the sequence. The light reflected by this door was enough to trouble the lightning when i decide too open it. I didn't notice any problem until i compile the shots.
For the third and last attempt, i put a light over the door of one of the building to add light and shadows. I pretty like the shadow of the character on the sidewalk when he passes in front of that door's light in the last part of the sequence.
Here it is
I shall change the lightning to have the rooftops darker.
